High-gloss thiab high-gloss yog cov khoom nyuaj rau cov tuam txhab txhaj tshuaj molding, vim tias lawv tsis tuaj yeem nkaum qhov tsis xws luag, thiab txawm tias cov plua plav hauv lub rooj cob qhia yuav ua rau muaj qhov tsis xws luag hauv cov khoom sib txawv, xws li trachoma, pitting, stains, thiab lwm yam. Kev ua qias tuaj, thiab lwm yam, yog li qhov chaw ib puag ncig kuj yog ib qho tseem ceeb cuam tshuam rau hom khoom no.

Cov pos huab dawb ntawm qhov chaw ntawm cov khoom yog dawb los ntawm qhov pom ntawm qhov pom, yog li nws tsis pom tseeb thaum nws yog cov khoom dawb, thiab cov ntsiab lus dub yog qhov pom tseeb tshaj plaws. Raws li pom nyob rau hauv daim duab 1, cov khoom yog ua los ntawm PP cov ntaub ntawv, thiab nyob ib ncig ntawm qhov chaw qhia tau hais tias ib tug loj loj thiab me me me me dawb, cov tsos mob zoo li huab, ntawm no yog cais raws li pos huab dawb.
2. Kev xav
Lub hauv paus theoretical tau los ntawm cov saum toj no yog tias muaj qee qhov sib txawv ntawm cov yas thiab cov yas thaum lub sij hawm pub mis, uas yog coj mus rau hauv lub thoob tom qab sheared los ntawm cov ntsia hlau. Thaum lub sij hawm shearing txheej txheem ntawm cov ntsia hlau, lub cev hloov pauv yuav tshwm sim nyob rau hauv cov khoom, los ntawm lub iav lub xeev Hloov mus rau hauv ib tug heev elastic xeev, los ntawm ib tug heev elastic xeev mus rau lub viscous kua.
Cov txheej txheem ntawm kev hloov pauv no tsuas yog nyob nruab nrab ntawm ob peb vib nas this - kaum ob vib nas this, (raws li qhov loj ntawm lub tshuab lossis cov khoom lag luam) hauv lub sijhawm luv luv los hloov cov txheej txheem nyuaj, kev txhaj tshuaj molding tsis zoo kuj tseem tshwm sim tam sim ntawd, thiab qhov sib txawv ntawm cov yas yuav raug compressed rau Gas yog tsim nyob rau hauv cov khoom molten. Yog tias cov roj tsis tuaj yeem tawm mus rau sab nraud ntawm lub thoob thaum lub sij hawm plasticization, cov roj uas twb muaj lawm yuav muab qhwv rau hauv cov khoom molten thiab txhaj rau hauv pwm kab noj hniav. Txawm hais tias cov pwm tuaj yeem tso tawm tau yooj yim yog nyob ntawm seb qhov tso tawm ntawm pwm puas zoo. , qhov tshwm sim ntawm fogging, gas trapping lossis scorching yuav tshwm sim.
Obviously, pos huab dawb kuj yog ib qho tshwm sim ntawm cov huab cua. Ntau tus neeg koom nrog kev txhaj tshuaj molding tshuab ua yuam kev ntseeg tias tsuas yog qhov kub hnyiab yog qhov ua rau muaj cua nkag, lossis tias nws tsis muaj kev tshawb fawb los qhib lub qhov hluav taws xob thaum muaj cua nkag. Kev kub nyhiab yog tshwm sim los ntawm Gas trapping yog hnyav heev, cov pa roj compressed nyob rau hauv lub siab thiab siab ceev thiab tsis tuaj yeem tso tawm, ua rau ib nrab combustion, thiab combustion kub tuaj yeem ncav cuag 600-800 degree hauv ib qho instant, uas yog qhov siab tshaj plaws. lub xeev ntawm trapped gas.

3. Kev daws teeb meem
Yuav ua li cas cov pa roj tau zoo tshaj plaws uas tsis muaj pos huab dawb?
1. Pwm
Cov pa paug tsis yog daws tau los ntawm cov pwm. Rau cov yam ntxwv ntawm cov khoom siv PP, qhov kub thiab txias yog qhov dav heev, thiab nws cov dej ntws zoo heev. Yog hais tias qhov tso pa tawm ntawm cov pwm loj dhau los yog txoj hauj lwm tsis raug, nws tsis tuaj yeem raug tshem tawm kom raug, thiab nws yooj yim ua rau ya. Cov sab tsis zoo, yog li kev tso pa kom zoo yog txhua yam tseem ceeb.
2. Khoom siv tes ua
Mastering cov txuj ci kho kom raug yog zoo heev hauv kev ua haujlwm tiag tiag.
1) Yog tias qhov kev sib hloov ceev ntawm cov ntsia hlau raug txo, qhov kub ntawm cov khoom molten tuaj yeem ua kom zoo ib yam, thiab lub caij nyoog ntawm cov cua nkag yog me me. Yog hais tias lub hau ntswj tig ceev heev, lub caij nyoog ntawm cov cua nkag yog ntau dua; Cov cua sov ua rau qhov kub ntawm cov yaj tsis sib npaug, thiab cov yaj decomposes los tsim cov roj.
2) Ua kom cov pwm kub tuaj yeem muaj txiaj ntsig zoo siab thiab ua kom qeeb kom tau txais lub sijhawm. Yog tias cov pwm kub qis dhau lawm, qhov saum npoo ntawm cov khoom tuaj yeem ua rau lub sijhawm khov, thiab tsis tuaj yeem ua tiav qeeb, uas yuav ua rau tsis muaj kua nplaum.
3) Txo qhov kev txhaj tshuaj nrawm, qhov nrawm nrawm dua, cov pa roj nrawm nrawm dua thiab qhov kub siab dua. Qhov qeeb qeeb, qhov qeeb ntawm cov pa compressed, thiab qhov yooj yim dua nws yog tso cov pa tawm.
4) Clamping quab yuam, qhov ntau dua lub clamping quab yuam, qhov ua rau lub zog ntawm cov kab noj hniav tsis zoo, thiab qhov me me ntawm lub clamping quab yuam, qhov zoo dua cov pa tawm ntawm cov kab noj hniav.
