Hauv kev lag luam plastics, feem ntau ntawm cov chaw tsim khoom tau ntsib cov teeb meem nrog cov nplaum nplaum: cov nplaum emit pungent, ntxhiab tsw thiab tsis zoo ib puag ncig; cov khoom sib koom ua ke tawg yooj yim thaum cuam tshuam; lub sij hawm curing ntev slows ntau lawm; Cov nplaum nplaum yog qhov nyuaj los ntxuav; thiab lawv ua tsis tau raws li cov kev cai sealing. Kev tshwm sim ntawm cov yas kub yaj tshuab tau hloov pauv cov txheej txheem kev sib txuas ntawm cov yas yas, ua rau lawv cov khoom siv tseem ceeb hauv cov tsheb niaj hnub no, cov khoom siv hauv tsev, lub zog tshiab, thiab cov khoom siv hluav taws xob. Ntau tus neeg ua haujlwm pem hauv ntej, cov neeg ua haujlwm yuav khoom, thiab cov kws ua haujlwm ua haujlwm nrog cov tshuab kub yaj txhua hnub tseem tsis tau paub txog cov ntsiab lus ntawm cov khoom siv no.
Cias muab, lub tshuab yas kub yaj yog tshwj xeeb vuam cov cuab yeej tsim los ntawm lub hauv paus ntsiab lus ntawm melting thiab 重组ing polymer plastics. Nws yog tsim tshwj xeeb rau cov khoom siv thermoplastic los ua cov txheej txheem xws li seamless welding, yas stud riveting, txiv ntseej embedding, thiab sprue tshem tawm. Nws tsis siv ib qho poob ntawm cov nplaum lossis ib qho ntsia hlau; los ntawm kev tswj qhov kub thiab txias thiab cua sov ua ke nrog lub siab tsis tu ncua, nws fuses ob qho tib si yas workpieces ua ke ntawm qib molecular, ua tiav ib qho kev sib koom ua ke.
Ntau tus neeg xav tias: yuav tsis cov yas ua nkig thaum nws txias tom qab cua sov thiab yaj? Qhov tseeb, qhov no tsis yog qhov tseeb. Cov thermoplastics muaj lub cev tshwj xeeb; Thaum rhuab mus rau lawv softening los yog melting kub, lub molecular chains ntawm lub yas nto qhib kiag li. Thaum ob lub workpieces nias ua ke, cov saw hlau molecular intertwine thiab entangle nrog ib leeg. Tom qab txias thiab teeb tsa, lub zog ntawm lub seam tuaj yeem tshaj li ntawm cov yas nws tus kheej. Muab piv rau cov nplaum, uas tsuas yog khi cov txheej txheej saum npoo, kub- melting welding fuses cov ntaub ntawv ntawm lawv cov tub ntxhais -qhov no yog qhov tseem ceeb vim li cas kub - melt welding deb tshaj cov nplaum nplaum nyob rau hauv cov nqe lus ntawm tensile zog thiab sealing kev ua tau zoo.
Cov khoom siv feem ntau raug xa mus rau hauv kev ua lag luam xws li kub- phaj vuam, yas kub- tshuab riveting, thiab kub- cov tshuab ziab txiv ntoo tag nrho yog cov tsev neeg dav ntawm cov yas kub- cov tshuab yaj, sib txawv hauv lawv cov txheej txheem tshwj xeeb. Tam sim no, kev tsim khoom hauv tsev tau nrawm rau theem - tawm ntawm cov txheej txheem nplaum nplaum. Ntawm ib sab, qhov no yog vim kev nruj lub teb chaws ib puag ncig cov cai thiab kev soj ntsuam nruj ntawm VOC emissions los ntawm cov tshuaj nplaum, muab cov kab ntau lawm ua rau muaj kev pheej hmoo raug yuam kom kho cov haujlwm lossis kaw. Ntawm qhov tod tes, cov kev xav tau zoo rau cov khoom kawg tau dhau los ua nruj dua; cov khoom siv xov tooj ntawm tes, lub teeb taws hauv tsheb, thiab cov khoom siv roj teeb lub zog tshiab txhua tus yuav tsum muaj siab -lub zog, tsis muaj dej, thiab airtight kev ua tau zoo- cov qauv uas cov nplaum nplaum tsis tuaj yeem ua tau raws li.
Niaj hnub no, yas kub- cov tshuab melting tsis yog niche lawm, tsis yog - cov khoom siv txheem tab sis cov cuab yeej siv rau kev tsim cov yas yas. Nyob rau hauv peb cov kev paub txog kev lag luam yav tom ntej, peb yuav muab cov txheej txheem sib xyaw ua ke, kev xaiv qauv, kev daws teeb meem, kev sib piv, kev saib xyuas, thiab kev lag luam daim ntawv thov- coj koj los ntawm kos mus rau kev paub txog cov yas kub- cov tshuab yaj thiab pab koj kom tsis txhob muaj kev cuam tshuam hauv kev tsim khoom, kev yuav khoom, thiab kev ua haujlwm.
