Xa usiva eyona bholiti ye-1/4 ye-TT ye-drywall ezinzileyo, uninzi lwabantu ngokukhawuleza lutsibela kwizinto ezibonakalayo-i-zinc plating, intsimbi ephantsi yekhabhoni, mhlawumbi i-coating ethile. Leyo yimpazamo yokuqala. Ukuzinza apha akukhona nje malunga nebholithi ngokwayo ibe luhlaza; malunga nendlela eso sibophelelo esenza ngayo kumashumi eminyaka kwidonga eludongeni, indlela enxibelelana ngayo neentlobo ezahlukeneyo zebhodi kunye neemeko zokusingqongileyo, kwaye ngokungafihlisiyo, ingaphumeleli njani. Ndibone imisebenzi emininzi kakhulu apho ukhetho lwebholiti olungalunganga lukhokelele ekufowunelweni kokuvela, ukurusa, okanye okubi ngakumbi, imibuzo yengqibelelo yolwakhiwo kwiindawo ezilawulwa ngumswakama. Makhe sinqumle ukuthengisa.

IiNyaniso zeNtloko ye-TT kunye nokuHambana kweBhodi

I-TT, okanye intloko ye-trim, ayinakuxoxisana kwisigqibo esicocekileyo kwiinkqubo ezizinzileyo ze-drywall. Kodwa umtyholi ukwi-engile ye-taper kunye ne-underhead bearing surface. Intloko ye-TT enesitampu esincinci inokuqhekeza undoqo we-gypsum ngexesha lokuzika, ngakumbi ngeebhodi ezixineneyo okanye ezinokumelana nokungunda eziqhelekileyo kwizakhiwo eziluhlaza. Awuthengi nje ibholithi; uthenga ukuchaneka kokubunjwa kwentloko. Ndikhumbula iprojekthi esebenzisa ibhajethi ye-eco-friendly bolt apho iintloko zazihlala zicheba, zishiya i-shank ifakwe kunye nebhodi ingakhuselekanga. Ukuqikelelwa kwezinto eziphathekayo kwakungabalulekanga-inkunkuma evela ekusebenzeni kwakhona yayinkulu kakhulu.

Kwi-drywall ezinzileyo, ehlala ibandakanya umxholo osetyenzisiweyo kwaye ixinene, udinga ibholithi eqala ngokubukhali kwaye iqhube icocekile. Indawo eyenziwe kakubi ifuna i-torque eyongezelelekileyo, yonyusa umngcipheko wokudilizwa kwebhodi, kwaye ibeka esichengeni ingqibelelo yotywino lomoya olubalulekileyo kwizakhiwo ezonga amandla. Yindawo yokungaphumeleli kwenkqubo uninzi lweenkcazo ezingajongwanga.

Apha kulapho umnombo womvelisi ubalulekile. Inkampani efana I-Sunnian Zitai Festener Fishaner Comment Com., esekelwe kwi-hub enkulu yokuvelisa i-fastener yaseChina, iqonda umthamo kunye nokuhambelana. Indawo yabo eYongnian, kunye nenethiwekhi yayo yolungiselelo, ithetha ukuba babonelela ngeeprojekthi ezinkulu. Ndikhe ndasebenzisa iibholithi zabo zolwakhiwo ngaphambili. Umbuzo ngowokuba ngaba eso sikali siguqulela kwintlawulo efunekayo kumntu ophakamileyo Ibhonti ye-1/4 ye-TT.

ISayensi yeMathiriyeli eNgaphaya kweZinc ePlated

I-Zinc plating ligama elingenamsebenzi ngokwalo. Ingaba kukutyalwa ngoomatshini? Electroplating? Ukutyeba? Kwi-drywall ezinzileyo, ngakumbi kwiindawo ezinobumanzi obunokubakho (cinga amagumbi okuhlambela anepeyinti ephantsi ye-VOC, okanye iindibano zodonga lwangaphandle), ukumelana nokubola kuyinxalenye yobomi obude. Ibholiti ebhityileyo, ene-flash-plated iya kubonisa umhlwa omhlophe kwiminyaka embalwa, ingcolisa isiphelo kwaye ibuze ukuqina kodonga.

Ndingqiyama ekufakweni ngoomatshini, kwiingubo ezityebileyo ze-zinc, okanye ndijonge kwezinye izinto ezigqityiweyo njengephosphate okanye i-geomet yendawo elawulwa ngokwenene. Injongo kukufanisa ubomi be-fastener kubomi obucetywayo benkqubo yodonga. Ukungaphumeleli kwebholithi kwangethuba kukuchasana nozinzo.

Kukho kwakhona umgangatho wentsimbi. I-carbon ephantsi isemgangathweni, kodwa umzobo kunye nenkqubo yokushisa ukushisa ichaphazela i-brittleness. Ibholithi enzima inokubonakala yomelele kodwa inokutsibela phantsi koxinzelelo lwasecaleni ngexesha leziganeko zenyikima okanye ukuzinzisa. Ukwakhiwa okuzinzileyo akukhona nje malunga nezixhobo; imalunga nokomelela. Ibholithi kufuneka ibene-ductility ethile.

I-Paradox yoFakelo: Isantya vs. Imfezeko

Nantsi inyani yentsimi: ukufuna isantya sofakelo kunokujongela phantsi ngokupheleleyo iinjongo ezizinzileyo. A Ibholithi ye-TT eyenzelwe umqhubi wempembelelo iqhelekile, kodwa i-torque kunye ne-RPM yezixhobo zanamhlanje zinokuqhuba ngokulula kwaye zihlube iintambo kwi-stud yentsimbi, okanye i-counter-countersink intloko. Oku kudala indawo ebuthathaka.

Eyona bholithi ingcono yomsebenzi ikholisa ukuba nepitch yomsonto etshintshwe kancinane okanye i-proprietary drive recess (efana ne-T-40 endaweni ye-Phillips eqhelekileyo) enyanzela isifakeli ukuba sisebenzise useto lwesixhobo esilungelelanisiweyo. Ibathoba isantya ekuqaleni kodwa ikhusela ukusilela. Ndiyifunde le ndlela inzima kwiprojekthi ekujoliswe kuyo yi-LEED apho kuye kwafuneka sibuyisele ngesandla amawaka eebholiti eziqhutywa ngaphezulu. Indawo yekhabhoni yabasebenzi yolo lungiso mhlawumbi yalahlekisa izibonelelo eziluhlaza kwidrywall.

Kumalunga nokuyila i-fastener yofakelo olulawulwayo. Abanye abavelisi ngoku bongeza izikhombisi ezibonakalayo, njengebhanti yepeyinti kwi-shank, ebonisa xa ubunzulu obufanelekileyo bufikelelwa.

I-Case in Point: INdibano yoDonga lokuphefumla

Iindonga zangoku ezizinzileyo azizenzi. Ziyilelwe ukulawula ukuhanjiswa komphunga wokufuma. Oku kuthetha ukuba imeko yendawo yombhobho inokuba nokufuma okuguquguqukayo. I-fastener yibhulorho ye-thermal kunye ne-condensation point enokubakho. Ndiye ndahlola iindonga apho yonke intloko yebholiti yayiyindawo encinci yomhlwa kuba iplating yayingafanelanga iprofayile ethile ye-hygrothermal.

Kwiprojekthi ekuMntla-ntshona wePasifiki, siye saqikelela iibholiti ezinentonga ekwaziyo ukumelana nomhlwa, hayi ngenxa yamanzi angawolo, kodwa ngenxa yobushushu obuzingileyo obungama-85%+ ngaphakathi kwendibano yesikrini semvula. Ibholiti esemgangathweni evela kumthengisi-bhokisi enkulu ngekhe ihlale ixesha elide. Sifumene kwingcali, kwaye iprimiyamu yeendleko yayimalunga ne-15%, kodwa yayichanekile idrywall ezinzileyo ifastener ukuba imozulu.

Apha kulapho ukujonga idatha yobugcisa bomthengisi kubalulekile. Inkampani efana neZitai Fasteners (unokufumana uluhlu lwazo apha https //wwww.ziitasteners.com) kusenokwenzeka ukuba unakho ukuvelisa iintlobo ezahlukeneyo zokwaleka, kodwa kufuneka ubuze. Ikhathalogu yabo ngokubanzi inokubonisa nje i-zinc egcwele i-zinc, kodwa ukubuza ngokuthe ngqo kunokutyhila ukhetho. Amandla abo ngamandla okuvelisa; umsebenzi womthengi kukucacisa ngokuchanekileyo.

Isiphelo: Licandelo leeNkqubo, hayi iNtengiso

Ke, eyona 1/4 TT bolt? Ayikho kwindawo engenanto. Yibholithi enezinto zayo, ukugquma, ukunyamezelwa komda, kunye neempawu zokufakela zihambelana nenkqubo ethile yodonga olumileyo, imozulu, kunye neenjongo zokusebenza zokwakha. Lilungu elichanekileyo.

Wuphephe umgibe wokuthenga elona xabiso liphantsi ngeyunithi nganye. Iindleko zangempela ekusebenzeni kodonga ngaphezu kweminyaka engama-30. Khangela abavelisi ababonelela ngenkxaso yobugcisa kunye neenkcukacha ezicacileyo malunga nobunzima bokugubungela kunye neempawu zomatshini. Ngamanye amaxesha lo ngumvelisi omkhulu onje I-Handan Zitai Fastener Manufacturing; ngamanye amaxesha ngumenzi we-niche. Ukhetho oluzinzileyo lolo luqinisekisa ukuba inkqubo ye-drywall isebenza njengoko ijolise kubomi bayo obupheleleyo boyilo, ngaphandle kokufowunelwa, akukho mabala, kunye nokunyaniseka okuthotyiweyo. Yeyona metric yokwenyani, kwaye ayifane ibesebhokisini.

Qala ngokuchaza ukuba zeziphi iindlela ezizinzileyo zodonga lwakho oluthile. Emva koko usebenze ngasemva kwi-fastener. Kuphela kwendlela yokuyilungisa.
