Polypropylene Yesigcilikisha kanye polyethylene

Polypropylene kanye polyethylene kukhona izinto, okuyinto okunzima ngempela ukunikeza e kunenze nisondelane. Uma ungawasebenzisi Welding, inqubo yokuxhuma izakhi ezimbili kuyoba yinkinga. Phakathi kwezinye izinto, evele kudingeka lwesikhashana ukulungiselela kokuqala. I ingcina ingase isetshenziselwe polypropylene kungenjalo.

Izinhlobonhlobo eyinhloko anamathelayo

Uma udinga i ingcina for plastic, kufanele wazi ukuthi iza flavour ezimbili: thermoset kanye nokusungulwa Thermoplastic. Ngenxa ngesisekelo isenzo epoxy wokuqala, ne-polyester thermoset resin. Isigaba sesibili anamathelayo zingahlukaniswa zibe izindawo ezimbili, eyokuqala yenziwa ngesisekelo iraba, kanti eyesibili - ngesisekelo inhlaka.

izingoma Thermoplastic ukuthambisa futhi chaza izinto ngaphansi kwethonya lokushisa. Uma eziqhathanisa thermosetting, engashintshi chemical yabo isakhiwo ngesikhathi kunenze nisondelane, okuyinto inzuzo enkulu. polypropylene Yesigcilikisha ingahlukaniswa ngisho futhi isibalo izingxenye Izingxube ingaba mono- noma bicomponent. Okokuqala esichazwa ngokuthi umkhiqizo osuphelile kwelinye iphakethe. Lezi zihlanganisa i-glue "Moment" I-polypropylene. A yesibili zahlanganiswa ngo amaphakheji ezimbili, ngalinye linegama izithako uhlanganise. Njengoba isibonelo, cabanga laqanjwa eyodwa ingxenye can Cosmoplast 500 esisetshenziselwa ukuxhuma amaphrofayli ewindini womshini. Uma udinga-ingxenye ezimbili, kungenzeka ukusebenzisa i ingcina epoxy for plastic elenziwe ngesisekelo agent sokwelapha futhi epoxy resin. ingcina Amabili ingxenye inebuhle, okuyinto kuvezwa obala isitoreji zesikhathi eside. Isizathu siwukuthi izithako ningangeni contact kanye sokwelapha ingekho phambi yokuxhuma.

Izici Main Cosmoplast ingcina 500

Le ncwadi eshiwo ngenhla polypropylene ingcina uba Ukwakheka eyodwa ingxenye angasetshenziswa e umkhakha nokuphila kwansuku zonke. It singasetshenziswa for kunenze nisondelane uxhumano i-engela 45 °. Lokhu uqweqwe kwakuphakeme kunemifuziselo yako e elifushane omiswe isikhathi. Ukwakheka olumelana amanzi, kushisa noma kubanda. Esondele omiswe isikhathi salo imizuzwana 3, futhi ngesikhathi sokwelapha kokugcina 20 ° C amahora 16.

Operating Imiyalelo 500 Cosmoplast

Uma unquma ukusebenzisa ingcina ngenhla achazelwe polypropylene, kufanele kuqala uthole ujwayelene ukusebenzisa kwayo. Sebenzisa ingxube kufanele kube kusuka yokulinganisa esitsheni noma kanye Cosmoplast bohlahleli izindlela okuyinto idivayisi metering. Isicelo kufanele kwenziwe ngakolunye uhlangothi ebusweni, okuyinto ngaphambili kudingeka ukuhlanza kusuka ukungcola nothuli, yomiswa. Yokuhlanza kungenziwa ngosizo amathuluzi esikhethekile uhlobo "Kosmofen 60". I evele xhumelela futhi equliswa ingcindezi isikhathi esibekiwe ngaphambi kokuba iphele ngaphandle. Ngenxa viscosity ongaphakeme sokuqanjwa echazwe ayikwazi ukumelana ukungezwani igebe sasondelana. Uma udinga ukuxhuma izikhala ezinkulu, ingasetshenziswa ngokuzikhethela Cosmoplast 564.

Ukuhlanza glue

I ingcina ngoba ukusondelana le polypropylene kungenzeka nahlanza eminye usebenzisa ukulungiselela nezasohshem "Kosmoplast 597". Ukugeza umthamo volumetric ka ingcina nezasohshego kwenziwe ngendlela efanayo. Uma ingcina isivele iphethwe ukuze ome out ke ungakwazi usule ngesandla ke. Lapho evele zimumethe kuphela, kokokunamathisela kungenziwa usubunile kakade lususwe.

Izici Zabantu izitembu sealant-ingcina Dow Corning 7091

Lokhu ingcina-sealant ngoba polypropylene kuyinto mass viscous uketshezi esisetshenziselwa seal amalunga Ukuvikelwa ezishelelayo ahlukahlukene. Ukwakheka ingasetshenziswa kunenze nisondelane izinto eyohlobo nomunye. Phakathi izici eyinhloko kokokunamathisela ungabahlukanisa, njengoba kulandela:

• ikhono seal futhi lezo izinto ezahlukene;
• ukufudumeza ukumelana;
• ukumelana imisebe ultraviolet;
• ukuqina;
• adhesion ePhakeme ukuba izinto ezahlukene;
• kuyaqina eziphakeme umphetho.

Kufanele kukhunjulwe ukuthi ingase sealant libhekene i acid sokwelapha uhlobo, lokhu kubonisa ukuthi ukwakheka unekhono ukwaba ethile acetic acid ngesikhathi solidification. Lokhu kungabangela ukubhujiswa izinsimbi non-ayoni futhi kwazo nokugqwala. Lokhu kufanele futhi ufake zemabula ezinye nezinye izinto. Lokhu ingcina sikhona yonke indawo, kulungile futhi kulula ukuyisebenzisa, has izimfanelo ukumelana amanzi ukumelana namakhemikhali kanye vibration. It kungenziwa eziqhutshwa ezingeni lokushisa kusuka -55 kuya +180 ° C. Lokhu uphulukisa glue kuya polypropylene esobala ngaso ekamelweni lokushisa, it has adhesion ezinhle ngaphandle priming eyengeziwe ngezinto ezivamile. Ukwakheka uyakwazi ukwenza indima ingcina ungqimba ukushuba 5 mm, ingasetshenziswa njengendlela sealant, uma ungqimba ukwakha-25 mm. Lapho usebenzisa limelela inductile pasty ukungaguquguquki. Ngemva kokuphothulwa isinyathelo lukhuni ukuvumelana ufana iraba nokunwebeka. Zezimfanelo kudingekile izonikezwa sealability materials eyohlobo nalabo ukuthi ahlukile ezishisayo ukunwetshwa Coefficient.

Kungani kufanele ukhethe brand sealant Dow Corning 7091

I ingcina ngenhla achazelwe polypropylene kanye polyethylene unezimfanelo uwoyela ukumelana, ukumelana umswakama, kuyaqina okusezingeni eliphezulu namandla. Kulula ukusebenzisa, phakathi kokunye, okwazi othola lokushisa kusuka -55 kuya +180 ° C.

Izici isicelo

I evele uphawu kumele degreased, bahlanza futhi omisiwe. Degreasing nge izihlanzi mhlawumbe uhlobo acetone noma utshwala isopropyl. Lemali edingekayo sealant okumele asetshenziswe komunye ngaphezulu, bese uxhuma lezisekelo ezimbili. Lungisa ilungiselelo mutual yezingxenye kungaba emizuzwini engu-15 emva isicelo kuze akha ifilimu is phezu Yesigcilikisha. Uma izimo ziyanakekelwa ukuze ekamelweni lokushisa kanye nomswakama isihlobo 50%, ijubane sokwelapha kuyoba ulingana 2 amamitha ngosuku. Uma okuqukethwe umswakama kuyehla, isikhathi solidification kuyokhula.

Izici WEICON Easy-Mix PE-PP bicomponent glue

Lokhu Ukwakheka inhlanganisela ezimbili ingxenye for kunenze nisondelane polyethylene ne-polypropylene. Wenziwe ngesisekelo acrylate, futhi amandla ingcina eliphezulu amapulasitiki ephansi amandla futhi Plastics. Kuyaphawuleka ukuthi ebusweni pretreated akudingekile. Lokhu Ukwakheka kuyisipho enemisebenzi, ngakho ingasetshenziswa ukuze kunenze nisondelane we-polyamide, polyvinyl chloride, polycarbonate, polymethyl methacrylate, kanye-fiberglass nezinye izinto.

isiphetho

Lapho usebenzisa eyodwa izingoma ngenhla ufuna unamatsisela amashubhu polypropylene, izinga lokushisa egumbini kufanele ibe uhla kusuka +5 ukuze +35 ° C. Okubalulekile ukuba isibhamu i-glue, ibhulashi nge bristles yemvelo, kanye umshini wokusika ipayipi. Ngaphambi kokufaka isicelo onqenqemeni izigaba ingcina kufanele esehlelembe, indlela kuphela uzokwazi ukuthola okusezingeni eliphezulu nokwethenjelwa umphetho.
