c, yooj yim molding txheej txheem

d. Cov xim zoo nkauj

e. Qhov tsis zoo tshaj plaws yog brittleness

f, kub-resistant kub yog tsawg (qhov siab tshaj plaws siv kub 60 ~ 80 degrees Celsius)

g, acid tsis kam

2,Polypropylene (PP). Nws yog xim tsis muaj xim thiab pob tshab lossis muaj qee yam luster granular khoom, hu ua PP, feem ntau hu ua cov roj hmab muag. Nws yog crystalline yas. Cov khoom ntawm polypropylene yog raws li nram no.

ib. Zoo flowability thiab zoo heev molding kev ua tau zoo.

b. Cov cua sov ua haujlwm zoo heev, tuaj yeem ua kom tsis muaj menyuam los ntawm kev npau npau ntawm 100 degrees Celsius

c. High yield zog; cov khoom hluav taws xob zoo

d. Kev nyab xeeb hluav taws tsis zoo; huab cua tsis zoo, rhiab heev rau oxygen, susceptible rau ultraviolet lub teeb thiab aging

3,Nylon (PA). Yog ib qho yas engineering, yog cov yas uas muaj polyamide resin, hu ua PA. muaj PA6 PA66 PA610 PA1010, thiab lwm yam. Cov khoom ntawm nylon yog raws li nram no.

a, nylon muaj lub siab crystallinity, siab mechanical zog, zoo toughness, siab tensile, compressive zog

b, zoo heev qaug zog tsis kam, hnav tsis kam, corrosion kuj, tshav kub tsis kam, tsis muaj tshuaj lom, zoo heev hluav taws xob khoom

c, tsis zoo lub teeb tsis kam, yooj yim nqus dej, tsis acid-resistant

4,Polyformaldehyde (POM). Kuj tseem hu ua cov khoom siv hlau sib tw, yog ib hom kev lag luam yas. Cov khoom thiab kev siv ntawm polyformaldehyde

a, paraformaldehyde muaj cov qauv crystalline heev, muaj cov khoom siv kho tshuab zoo heev, siab modulus ntawm elasticity, rigidity thiab deg hardness kuj siab heev, hu ua "hlau sib tw"

b. Me me coefficient ntawm kev sib txhuam, zoo heev hnav tsis kam thiab nws tus kheej lubrication, thib ob tsuas yog nylon, tab sis pheej yig dua nylon

c, zoo hnyav kuj, tshwj xeeb tshaj yog cov kuab tshuaj organic, tab sis tsis muaj zog acids, muaj zog alkalis thiab oxidizers

d, zoo seem stability, muaj peev xwm tsim precision qhov chaw

e, molding shrinkage, thermal stability tsis zoo, cua sov yooj yim rau decompose

5,Acrylonitrile-butadiene-styrene (ABS). ABS yas yog lub zog hloov kho polystyrene, muaj li ntawm acrylonitrile, butadiene thiab styrene nyob rau hauv ib qho piv txwv ntawm peb lub tebchaw, nrog lub teeb ivory, opaque, non-toxic thiab tasteless.

Cov yam ntxwv thiab kev siv

ib. High mechanical zog; muaj zog cuam tshuam; zoo creep kuj; nyuaj, tawv, nruj, thiab lwm yam.

b, Qhov chaw ntawm ABS yas tuaj yeem plated

c 、 ABS tuaj yeem sib xyaw nrog lwm cov yas thiab roj hmab los txhim kho nws cov kev ua tau zoo, xws li (ABS + PC)

6, Polycarbonate (PC). Feem ntau hu ua bulletproof iav, yog ib qho tsis muaj tshuaj lom, tsis qab, tsis muaj ntxhiab, cov khoom pob tshab, combustible, tab sis tuaj yeem tua tus kheej tom qab tawm hauv hluav taws. Cov yam ntxwv thiab kev siv.

ib. Nrog tshwj xeeb toughness thiab hardness, nws muaj qhov zoo tshaj plaws kev cuam tshuam lub zog ntawm tag nrho cov ntaub ntawv thermoplastic

b. Zoo heev creep kuj, zoo seem stability, siab molding raug; zoo kub tsis kam (120 degrees)

c. Qhov tsis zoo yog lub zog qaug zog tsawg, muaj kev ntxhov siab sab hauv, yooj yim rau tawg, thiab hnav tsis zoo ntawm cov khoom yas.

7,PC + ABS alloy (PC + ABS). Combined PC (engineering plastics) thiab ABS (general-purpose plastics) qhov zoo ntawm ob qho tib si, txhim kho kev ua tau zoo ntawm ob qho tib si. Muaj ABS thiab PC tshuaj muaj pes tsawg leeg, nrog ABS zoo fluidity thiab molding processability, PC cuam tshuam thiab tsis kam mus rau kub thiab txias hloov. Nta

ib. Tau dispensed nrog kua nplaum qhov ncauj / dej loj qhov ncauj pwm tsim.

b 、 Nto tuaj yeem txau cov roj, plating, hlau txau zaj duab xis.

c. Nco ntsoov qhov sib ntxiv ntawm qhov tso pa tawm.

d. Cov khoom siv feem ntau yog siv hauv cov pwm kub khiav thiab tau siv ntau thiab ntau cov khoom siv sib txuas lus, xws li cov xov tooj ntawm tes / khoos phis tawj.
