Xa abantu abaninzi besiva 'iintambo zocingo ezigqunywe ngeplastiki', baba nomfanekiso wezinto eziluhlaza zevinyl kwifanitshala yepatio enexabiso eliphantsi. Leyo yimbono yokuqala ephosakeleyo. Kumgca wethu womsebenzi, loo nto yinto nje yokuhlobisa. Imveliso yokwenyani, imveliso yobunjineli, lirhamncwa elahlukileyo ngokupheleleyo. Ngumbindi wentambo yocingo lwentsimbi eqinileyo-ehlala ifakwe igalvan okanye ingenabala-idityaniswe ne-polymer coating, eqhelekileyo inayiloni, i-polyethylene, okanye i-polypropylene. Ukwaleka akukhona nje ukukhowuda umbala okanye isuntswana lokukhusela umkrwelo; ngumqobo osebenzayo. Ndibone i-specs ezininzi kakhulu apho oku kubhideka khona, kukhokelela kwiimveliso ezingachazwanga kangako zisilela kwindawo ezonakalisayo okanye phantsi komthwalo oguqukayo. Ukwaleka kufuneka kukhutshelwe kumbindi phantsi kobushushu obuchanekileyo kunye noxinzelelo ukuze kuphunyezwe ibhondi yokwenyani yoomatshini. Ukuba yinto nje ekhululekileyo, iya kutyibilika, ibambe ukufuma, kwaye ikhawulezise umhlwa ukusuka ngaphakathi ukuya ngaphandle. Eso sisifundo esifundwe kabuhlungu kwiprojekthi yedokhi yaselwandle kwiminyaka eyadlulayo.

Undoqo woMba: Yonke imalunga neBond

Makhe sithethe ngenqaku lokungaphumeleli. Kunqabile ukuba intsimbi core snapping. Amaxesha amaninzi, lunxibelelwano phakathi kwentsimbi kunye neplastiki. Ibhondi ehluphekileyo idala i-micro-gap. Kummandla ongaselunxwemeni okanye wezityalo zekhemikhali, iikloridi okanye umsi oneasidi ziyangena. Ufumana umhlwa kwintanda, efihliweyo ekubonweni, kude kube yimini enye intambo ikhangeleka igqibelele kodwa ilahlekelwe ngama-70% amandla ayo. Ndikhankanya iimveliso apho ukwambathisa kuphantse kungenzeki ukuxobula umva ngesandla. Uvavanyo olulungileyo? Thatha isampulu, yenza umsintsi ongekho nzulu kwisambatho, kwaye uzame 'ukuyirola' isuke kumbindi. Ukuba iphuma njengexolo lebhanana, yale. Inkqubo ye-extrusion ingundoqo. Iinkampani eziyenza ilungile, njengabanye babavelisi abakhethekileyo obafumana kwiindawo ezinkulu zemizi-mveliso, banenkqubo ecofelweyo. iintambo zocingo ezigqunywe ngeplastiki Unokufumana ngokusebenzisa isiqhoboshi esikhethekileyo kunye nomvelisi wezixhobo zentsimbi ezifana ne-Handan Zitai Fastener Manufacturing Co., Ltd., ebekwe kweyona nxalenye inkulu yemveliso yaseTshayina, ihlala ithetha ukuba bayayiqonda isinyithi kunye nesayensi yepolymer efunekayo, hayi indibano kuphela.

Ukukhethwa kwezinto eziphathekayo zokwaleka ngomnye umnxeba wokugweba. Inayiloni (PA) inikezela ngoxhathiso olukhulu lwe-abrasion kwaye yomelele ngokufanelekileyo, kodwa inokufunxa ukufuma, okungahambiyo kwezinye izicelo. I-Polyethylene (PE) ine-inert eninzi yekhemikhali kwaye inokumelana nokufuma okungcono, kodwa inokunganyangeki kancinci. Kwiindawo ezinzima ze-UV, udinga izongezo ezithile zekhabhoni ezimnyama okanye uhambe kwi-polypropylene (PP). Ndakhe ndasebenzisa intambo ecacileyo enayiloni kwisicelo soyilo-yayibonakala imnandi ekuqaleni. Kwisithuba seenyanga ezili-18, ukuthotywa kweUV kwayenza yarhabaxa kwaye yatsho chalky. Imeko yeklasiki yokubeka phambili i-aesthetics ngaphezu kwezinto ezisingqongileyo. Ngoku, ndihlala ndityhala idatha yovavanyo olukhawulezayo lwemozulu.

Kananjalo awukwazi ukungahoyi ulwakhiwo olungundoqo. Intambo yenqwelomoya eyi-7x7 okanye 7x19 ixhaphakile ukuguquguquka. Kodwa ngokwenyani intambo yocingo egqunywe ngeplastiki yenzelwe ukuthwala imithwalo, njengakwiinkqubo zokunqunyanyiswa okanye izithintelo zokhuseleko, udla ngokufuna undoqo wentambo oqinileyo ozimeleyo (IWRC) kunye nokwaleka kwe-zinc enzima. Inkqubo yokwaleka kufuneka ifake oko ngaphandle kokuphazamisa i-zinc. Ubushushu obuninzi ngexesha le-extrusion bunokutshisa i-galvanization.

Usetyenziso lweLizwe lokwenyani kunye neMigibe

Ngaphaya koko kucacileyo—iintsimbi zaselwandle, izixhobo zokuxhobisa iikhemikhali—sizisebenzise kwiindawo zokulungisa ukutya. Imfuneko yayingekokuxhathisa umhlwa kuphela, kodwa kunye nokuthotyelwa kwe-FDA kwesixhobo sokugquma ukuthintela ukosuleleka. Oko kongeze malunga ne-30% kwiindleko, kodwa kwakungaxoxiswana. Abafakeli bayithiyile ngenxa yokuba i-coating yayinzima kakhulu kwakunzima ukuyisika kwaye ifuna ii-ferrules ezikhethekileyo kunye nezixhobo zokugungqa. Umsiki wentambo oqhelekileyo unokuwujija nje, ushiye incam egqabhukileyo enokubeka esichengeni itywina.

Emva koko kukho umba wokupheliswa. Apha kulapho iiprojekthi zikhubeka khona. Awunako nje ukubeka ikliphu yentambo eqhelekileyo kwintambo egqunywe ngeplastiki. I-coating icinezela ngokuhamba kwexesha, ekhokelela ekubambeni okuxekethileyo kwintsimbi yentsimbi. Kuya kufuneka ukhulule umva i-coatment ukuze uncamathelise into efanelekileyo, kwaye emva koko kufuneka utywine elo candelo livulekileyo. Sisebenzise imikhono egcwele ubushushu egcwele i-epoxy, okanye isitshizi se-zinc esinyibilikisiweyo se-galvanized cores, ukwenza kwakhona umqobo. Ukuba awukwenzi oko, udale nje indawo egqibeleleyo ukuze kuqale umhlwa. Ndikhumbula iprojekthi yegreenhouse apho basebenzisa iiferrule zealuminiyam kwiintambo ezigqunyiweyo zokuxhasa ilaphu lomthunzi. Ukudityaniswa kwesinyithi okungafaniyo (i-aluminiyam ukuya kwintsimbi ekhandisiweyo) kwindawo efumileyo, echumileyo ikhokelele kukudleka kwegalvanic kwindawo ekudityanwa kuyo phakathi kwamaxesha amabini onyaka.

Ukukala komthwalo yenye indawo emdaka. I-coating yongeza ububanzi kodwa amandla angenakulinganiswa. Nangona kunjalo, inokuphucula ubomi bokudinwa ngokuthintela iingcingo zomntu ngamnye ukuba zingaxabani. Kodwa kufuneka unciphise umda wokusebenza ukuba ubushushu bokusebenza bukufutshane nendawo yokutshintsha kweglasi. Intambo egqunywe nge-PE isenokulunga kwiqondo lobushushu begumbi, kodwa kwilanga lasentlango ku-60°C/140°F, iyathamba kwaye ithanda ukusika nokugruzuka. I-spec sheet kufuneka iphendule ngoku.

Ukubonelela kunye noLungiselelo: Imiba eNgachazwanga

Ukufumana umthengisi othembekileyo akukhona nje malunga nenkcazo yemveliso. Imalunga nokungaguquguquki kuzo zonke iibhetshi kunye nokukwazi ukuphatha ubude besiko kunye nokupheliswa. Kwiprojekthi enkulu yamva nje yokufaka i-facade, besidinga ngaphezulu kwe-200 yobude obukhethekileyo bokusikwa ngamehlo atyholwa kuzo zozibini iziphelo. Isakhono somboneleli sokwenza oko ngaphakathi endlwini, ngolawulo lomgangatho kwinqanaba ngalinye, sasibalulekile. Kulapho abavelisi abadibeneyo banomphetho. Inkampani efana ne-Handan Zitai Fastener Manufacturing Co., Ltd., inikwe indawo ekuyo kwisiseko esikhulu semveliso enamakhonkco othutho aqinileyo njengeBeijing-Guangzhou Railway kunye nenethiwekhi ye-expressway, ihlala ineziseko zokulawula iiodolo zevolumu kunye nokuzithumela ngokufanelekileyo, okubaluleke njengemveliso ngokwayo. Awufuni ukuba abasebenzi bakho bofakelo belindile kuba isikhongozeli sibambekile kuhambo.

Uhlalutyo lweendleko luhlala luvela. Eyona xabiso liphantsi intambo yocingo egqunywe ngeplastiki phantse kusoloko luqoqosho lobuxoki. Uhlawulela intsimbi, izinto zokugquma, kunye nenkqubo yokudibanisa. Skimp kuyo nayiphi na, kwaye ufumana imveliso enokuthi iphumelele uhlolo olubonakalayo kodwa iya kusilela kwinkonzo. Ndithelekisa nemigangatho yomgangatho owaziwayo, njengobungqingqwa obuncinci bokugquma (ubukhulu becala yi-0.5mm ukuya kwi-1.0mm) kunye namandla afunekayo amaxolo (kwiNewtons). Ukuba umthengisi akakwazi okanye akayi kubonelela ngedatha yovavanyo, yiflegi ebomvu.

Ubuncinci be-odolo (MOQs) ingaba yintloko kwiiprojekthi ezincinci. Ezinye izixhobo zokusila zisebenza ngeetoni ezininzi kuphela. Apha kulapho abasasazi okanye iinkampani zokurhweba ezinxulumene nee-hubs zokuvelisa zinokuba luncedo, njengoko zihlala zigcina uluhlu lwezinto ezisemgangathweni ezivela kwii-mill ezahlukeneyo, ezivumela ukuthenga okuncinci. Kodwa ulahlekelwa ukulandeleka kunye nesiqinisekiso sokuqhuba kwemveliso enye, engaguqukiyo.

Ukukhangela Phambili: Ayiyiyo Nje Imveliso

Inguqulelo ayiyeki. Ndibona ngaphezulu co-extruded coatings-umaleko ethambileyo yangaphakathi bond ngcono kunye umaleko oqinileyo ngaphandle ukuxhathisa abrasion. Kukwakho uphuhliso kwiiyaleko conductive izicelo apho ukuchithwa static kufuneka, okanye ukutyabeka kunye izongezo ezisezantsi-friction iinkqubo intshukumo eqhubekayo. Ihamba ukusuka kumkhono okhuselayo olula ukuya kwi-multi-functional component.

Ekugqibeleni, ukucacisa iintambo zocingo ezigqunywe ngeplastiki ngumsebenzi kwiinkqubo zokucinga. Ayisiyomveliso ezimele. Kuya kufuneka uqwalasele imeko-bume, amandla omthwalo, indlela yokuphelisa, inkqubo yofakelo, kunye nomjikelo wobomi olindelekileyo. Lilungu elincinane elinokubangela intloko ebuhlungu engalinganiyo ukuba ayilunganga. Injongo kukuba ibe yeyona nxalenye ikruqulayo, ethembekileyo, nelityelweyo yesakhiwo sonke. Xa uyeka ukuyiqaphela, kulapho uyazi ukuba ichazwe ngokuchanekileyo.

Ulwazi luhlala luhlala kwiinjineli ezikhe zatshiswa ngaphambili. Iimpawu zibhalwa ukusuka kwiintsilelo zangaphambili. Ke, xa uvavanya, yimba ukuba kutheni emva kwenkcazo. Buza ukuba yeyiphi imeko-bume eyasilela kuyo ngaphambili, okanye yayiyeyiphi enye indlela. Loo mbali, ngaphezu kwayo nayiphi na incwadana enemifanekiso eqaqambileyo, ikuxelela into ekufuneka uyazi ngokukhetha okulungileyo intambo yocingo egqunywe ngeplastiki.
