I-foam gasket tape

I-Polyurethane Foam- Lokhu akuyona nje enye indlela eshibhile enjoloba. Imvamisa kunokungaqondi ukuthi lesi yisixazululo sendawo yonke, futhi ekugcineni bakhetha izinto ezingafanele zomsebenzi othile. Bengisebenza nalezi zinto zemibhalo iminyaka eminingi, futhi ngingasho ukuthi kulungile ukukhethaUngqimba kusuka ku-polyurethane foam- Lokhu kuwubuciko bonke. Kubalulekile ukubheka hhayi hhayi kuphela izici zomzimba, kodwa futhi nezici zemvelo. Eminyakeni embalwa edlule, sasibhekene nenkinga ekukhiqizeni isakhiwo esiyinkimbinkimbi semishini, lapho ama-gaskets ajwayelekile enjoloba ahluleka ukumelana. Ngemuva kwalokho sashintshela ePPU, kodwa, singaphampuma, sakhetha ukwakheka okufiselekayo isikhathi eside saze sabona ukuthi kubalulekile hhayi kuphela ubunzima kuphela, kodwa futhi nokuqina kwe-polyurethane kuphela.

Kuyini ukwakheka kwe-polyurethane Foam futhi kuqukethe ini?

Okokuqala, ake sibheke ukuthi lokhu kungokwejwayelekile kuyini.Poliuretan Foam- Le yi-polymer Foam etholwe ngenxa yokusabela kwamakhemikhali phakathi kwama-polyol kanye nama-isocyanates. Idizayini ye-polyurethane Foam yehlukile: kusuka eziguquguqukayo futhi iqonde ku-Hard and Eastic. Kubonga ngezinhlobonhlobo zobunzima nesakhiwo,Izingqimba ezivela ku-polyurethane FoamBayakwazi ukwenza imisebenzi ehlukahlukene: ukubekwa uphawu, ukwehla, ukudonswa kokudlidliza, ngisho nokushisa nokufakelwa okuzwakalayo. Kubalulekile ukuqonda ukuthi 'I-Polyurethane Foam' iyisigaba sezinto ezibonakalayo, hhayi umkhiqizo onobunzima. Kunezinhlobo ezahlukahlukene ezihlukile ngobuningi, ukuqina, empafini kanye namanye amapharamitha.

Ukwakheka kwe-PPU kufaka hhayi kuphela izakhi ze-polymer, kodwa futhi nezithasiselo: ama-filler (ngokwesibonelo, i-talc noma ushoko), izinkundla, ama-antioxidants, ama-antioxidants, ama-antioxidants, ama-antioxidants, ama-antioxidants. Ukwakheka kwalezi zengezo kuthinta izakhiwo zomkhiqizo wokugcina. Isibonelo, ukungeza i-talc kukhulisa ubunzima futhi kuthuthukisa izici zemishini, futhi ama-antioxidants avikela impahla ekubhujisweni ngaphansi kwethonya lemisebe ye-ultraviolet kanye nezinto zomoya. Ngincoma njalo ngicela ipasipoti esezingeni eliphakeme kusuka kumphakeli, lapho ukwakheka kwezinto okukhonjiswa khona ngokuningiliziwe.

Izinhlobo zama-gaskets ezivela ku-polyurethane Foam: Ukukhetha kwemisebenzi ehlukene

Kunezinhlobo ezahlukeneIzendlalelo zePolyurethane Foamihloselwe izinhloso ezihlukile. Okuvame kakhulu: ifulethiama-gaskets, iringithaama-gaskets, ama-gasketsukwakheka okuyinkimbinkimbi, futhi okukhethekileama-gasketsngezinto ezihlanganisiwe zokubopha. Ukukhethwa kohlobo kuncike ku-geometry yokuxhumeka, ukuqina okudingekayo, kanye nezimo zokusebenza.

Isibonelo, ukubekwa uphawu ezinhlelweni ze-hydraulic, ringama-gasketsNgokumelana okuphezulu kumafutha nama-sol. Ukwakha izakhiwo zokwehla kobunjiniyela bemishini, khethaama-gasketsngobuningi obuphansi kanye nokuqina okuphezulu. Kanye nokufakelwa okunengqondo, njengoba isipiliyoni sethu ngezinhlelo zomoya wezimboni zikhombisile, zilungele kahleama-gasketsNgesakhiwo se-porous esidonsa ngempumelelo umsindo. Empeleni, inhlanganisela yezinhlobo ezahlukahlukene kwesinye isikhathi iyadingeka ukufeza umphumela ofanele.

Yini okufanele uyinake lapho ukhetha ukwakheka okuvela kuPolyurethane Foam?

EnqumaUngqimba kusuka ku-polyurethane foam, kufanelekile ukunaka amapharamitha asemqoka ambalwa: Ubunzima, ubulukhuni (esikalini esifushane noma esifushane), ukuguquguquka komthwalo, uhla lokushisa lokusebenza, ukumelana kwamakhemikhali, futhi, usayizi kanye nokwakheka. Ubukhulu bunquma amandla okwenziwa ngemishini nokumelana nokucindezelwa. Ukuqina kuthinta ukuqina kanye nekhono lokumelana nemithwalo. Ukuguqulwa komthwalo kukhombisa ukuthi i-gasket izocindezelwa kangakanani ngaphansi kwethonya lengcindezi. Kubalulekile ukuqiniseka ukuthi lokho okuqukethwe kumelana nemiphumela yezinto ezizoxhumana nazo (uwoyela, ama-acid, ama-solvents, njll.).

Elinye iphuzu elibalulekile ubukhulu be-gasket. Kumele ihambisane nemvume phakathi kwezindawo eziphekiwe. Ukubekwa okuncane kakhulu ngeke kunikeze ukuqina okudingekayo, futhi ubukhulu kakhulu kungaholela ekugcwalisweni ngokweqile nasekubhujisweni ngaphambi kwesikhathi. Kubalulekile futhi ukuthi ucabangele ukuthi uluphi uhlobo lokuxhumeka olusetshenziswayo (ngokwesibonelo, ukuxhumana okuyisicaba, ukuxhumana okunentambo, njll.). Ngohlobo ngalunye lokuxhuma, olukhethekileama-gaskets.

Isipiliyoni kanye nezinkinga okungenzeka

Emhlanganweni wethu, i-handan zitai i-fastener Manuapacturn Co, Ltd, sivame ukuhlangana nemibuzo ehlobene nokukhethwa kanye nesiceloIzendlalelo zePolyurethane Foam. Sikhiqiza uhla olubanzi lwama-fasteners futhi luvame ukusebenzisa leziama-gasketsEmiklamo yethu. Isibonelo, ekwenziweni kwamadivayisi aphezulu embonini yezobunjiniyela, sihlala sikhethaIzingqimba ezivela ku-polyurethane FoamNgosayizi omkhulu wokunemba nezinto ezizinzile zemishini. Lapho usebenza ngezindawo ezinolaka (ngokwesibonelo, ngama-acid kanye ne-alkali), sisebenzisa okukhethekileama-gasketsyenziwe kusuka ku-PPU ephikelelayo yamakhemikhali.

Noma kunjalo, ungakhohlwa ngezinkinga ezingaba khona. Ngokwesibonelo,Izingqimba ezivela ku-polyurethane Foamingabhujiswa ngaphansi kwethonya lemisebe ye-ultraviolet. Ngakho-ke, lapho kusebenza ngaphandle, kunconywa ukuyisebenzisaama-gasketsNgezengezo ezivikela emisebeni ye-UV. Futhi, ngokukhetha okungalungile kwezinto ezibonakalayo noma ngokufakwa okungafanele,Izingqimba ezivela ku-polyurethane FoamBangahluleka ngokushesha. Isibonelo, sake senza iphutha lapho sikhethaama-gasketsngohlelo lwe-hydraulic. Sikhethe ithambile kakhulugasselaokhubazeke ngokushesha ngaphansi kwengcindezi. Ngenxa yalokhu, kwakukhona ukuvuvukala kwamafutha futhi kwakudingeka ukuthi kuthathwe lonke uhlelo.

Ezinye izindlela zokuthuthuka namathemba wokuthuthuka

Vele, kunezinye izinto zokwakha ezingasetshenziswa njengeama-gaskets: irabha, i-silicone, teflon, yensimbi. Noma kunjalo,Poliuretan FoamNgokuvamile kuyisinqumo esihle kakhulu ngenxa yokusebenzisana kwayo kanye nenhlanganisela yezakhiwo ezahlukahlukene. Inkomba njengamanje ikhula ngenkuthalo ukudalaIzendlalelo zePolyurethane FoamNgezici ezithuthukisiwe: Ngokukhulisa ukumelana kokushisa, ukumelana kwamakhemikhali, kanye nokuvimbela ukumelana. Isibonelo, athuthukiswaama-gasketsKuhloswe ukuthi kusetshenziswe ezimweni ezimbi kakhulu - emazingeni okushisa aphezulu, ingcindezi, nasezindabeni ezinolaka.

Ekuphetheni, ngifuna ukugcizelela ukuthi ukukhethaIzingqimba ezivela ku-polyurethane Foam- Lo ngumsebenzi obhekele ngokudinga ukuhlaziya ngokuphelele kwazo zonke izinto. Ungagcini ngekhwalithi yezinto ezibonakalayo, ngoba ukuthembeka nokuqina komklamo wakho kuya kukho. Xhumana njalo abahlinzeki abathembekile bese ubacela amadokhumenti obuchwepheshe nezincomo ukuze zisetshenziswe.

Insizakalo kanye nokunwetshwa kwempilo yenkonzo

Inkonzo EfaneleIzendlalelo zePolyurethane FoamIdlala indima ebalulekile ekunwetshisweni kwempilo yabo yenkonzo. Bheka isimo njaloama-gasketsngomonakalo, imifantu kanye nokugqoka. Uma kunesidingo, buyisela okonakeleama-gaskets. Gwema Ukuxhumanaama-gasketsngezinto ezinolaka ezingalimaza lokho okuqukethwe. Khwezaama-gasketsEndaweni eyomile, epholile, evikelwe elangeni eliqondile. Ukuhambisana nale mithetho elula kuzokusiza ugweme ukulungiswa okubizayo futhi unwebe impilo yakho yensizaIzendlalelo zePolyurethane Foam.
