I. Cov hwj huam yas sib koom tes yas feem ntau ua los ntawm polyethylene (PP), thiab polyester (nrog rau cov tshuaj tiv thaiv cov organic tsim nyog. Lawv tom qab ntawd rhuab kub thiab tsim los ntawm cov txheej txheem xws li tshuab moulding, extrusion tshuab moulding, lossis txhaj tshuaj moulding. Cov ntaub ntawv uas nquag siv suav nrog tsiaj, PP, Abs, li, thiab Acrylic, txhua tus nrog cov yam ntxwv hauv qab no:
TSIAJ: cov khoom siv ib puag ncig uas muaj peev xwm hu ncaj qha rau cov ntsiab lus. Nws muaj qhov zoo xws li cov teeb meem siab, lub teeb ci ntsa iab thiab tsis yooj yim tawg, siab pob tshab; Txawm li cas los xij, nws qhov tsis zoo yog qhov tsis zoo - kub tsis kam, yooj yim deforming ntawm ambient kub siab tshaj 40 degree.
PE: Yog cov khoom siv ib puag ncig uas muaj peev xwm hu ncaj qha rau cov ncauj lus, siv ib qho kev ua tiav molding, cov khoom tiav yog tsim tau ncaj qha tom qab txhaj. Txawm li cas los xij, nws cov nplaim hluav taws xob muaj cov qauv matte, nrog tsawg dua tus tsiaj, lub raj mis npau taws, thiab tsis tuaj yeem ua tiav cov nyhuv pob tshab; Tsis tas li ntawd, cov nplaim hluav taws xob tsis haum rau cov xim pleev xim (txheej yog nquag mus rau teeting tawm), thiab txawm tias yog rau tshuaj ntsuam luam ntawv, yuav tsum muaj kev kho mob kub tshwj xeeb.
PP: Ib puag ncig phooj ywg thiab tuaj yeem hu ncaj qha rau cov ntsiab lus. Nws muaj qhov ceev qis thiab yog superior rau tsiaj hauv lub zog, rigidity, hardness, thiab cua sov kuj, thiab tuaj yeem siv thaum nyob ib ncig ntawm 100 degree. Txawm li cas los xij, nws dhau los ua lub zog ntawm tsawg kub thiab tau tsis zoo ua tsis kam, yog li nws feem ntau cov khoom siv rau kev pleev tshuaj pleev ib ce.
ABS: Lub siab {{0} {}} lub zog, tawv, thiab yooj yim ua cov khoom siv thermoplastic polymer. Nws tseem muaj corrosion tsis kam thiab siab- kub kuj, thiab feem ntau siv los ua cov khoom lag luam. Cov khoom lag luam ABS cov khoom muaj cov khoom du, ua rau lawv yooj yim kom zas thiab hluav taws xob. Cov khoom siv no feem ntau siv rau cov kaus mom xav tau electroplating thiab ob npaug - zoo nkauj fircare thiab kev zoo nkauj fwj.
Raws li: piv rau ABS, raws li muaj qhov zoo dua pob tshab thiab zoo dua.
Acrylic: Ua tsim kev txhaj tshuaj molding, nws muaj cov tshuaj tsis zoo thiab feem ntau tsis tuaj yeem siv ncaj qha los tuav cov cream; Yuav tsum muaj lub liner sab hauv. Nws yuav tsum tsis txhob noj ntau thaum lub sijhawm puv los tiv thaiv cov tshuaj pleev los ntawm kev pom ntawm lub pob hluav taws xob sab hauv thiab cov kab pleev xim acrylic, ua rau tawg. Yuav tsum muaj cov ntim tau siab yog tsim nyog thaum lub sijhawm thauj mus los, raws li cov khawb npoo saum npoo yog pom tau. Cov khoom siv tau yooj yim pob tshab, muab lub raj mis ua kom pom cov ntsej muag, tab sis nws yog tus nqi nkaus.
