Txhua yam uas tuaj yeem txhim kho cov khoom qub ntawm cov resin los ntawm lub cev, kev siv tshuab thiab tshuaj lom neeg tuaj yeem hu uakev hloov kho yas.Lub ntsiab lus ntawm kev hloov kho yas yog dav heev.Thaum lub sijhawm hloov kho, kev hloov pauv ntawm lub cev thiab tshuaj lom neeg tuaj yeem ua tiav.

Cov kev siv feem ntau ntawm kev hloov kho yas yog raws li hauv qab no:

1. Ntxiv cov tshuaj hloov kho

a.Ntxiv me me-molecule inorganic lossis organic teeb meem

Inorganic additives xws li fillers, reinforcing agents, nplaim retardants, colorants thiab nucleating agents, thiab lwm yam.

Organic additives xws li plasticizers, organotin stabilizers, antioxidants thiab organic flame retardants, Degradation additives, thiab lwm yam. Piv txwv li, Topfeel ntxiv degradable additives rau ib co PET fwj kom ceev tus nqi degradation thiab degradability ntawm plastics.

b.Ntxiv cov tshuaj polymer

2. Kev hloov kho cov duab thiab cov qauv

Txoj kev no tsuas yog tsom rau kev hloov kho cov ntaub ntawv thiab cov qauv ntawm cov yas nws tus kheej.Txoj kev niaj zaus yog hloov pauv lub xeev ntawm cov yas, crosslinking, copolymerization, grafting thiab lwm yam.Piv txwv li, styrene-butadiene graft copolymer txhim kho qhov cuam tshuam ntawm PS khoom.PS feem ntau yog siv nyob rau hauv vaj tse ntawm TVs, khoom siv hluav taws xob, ballpoint cwj mem tuav, lampshades thiab tub yees, thiab lwm yam.

3. Kev hloov kho vaj huam sib luag

Kev hloov pauv ntawm cov yas sib xyaw yog ib txoj hauv kev uas ob lossis ntau txheej ntawm cov yeeb yaj kiab, cov ntawv txheeb thiab lwm yam khoom sib xyaw ua ke los ntawm cov nplaum los yog kub yaj los ua ntau txheej zaj duab xis, ntawv thiab lwm yam ntaub ntawv. yas cosmetic raj thiabaluminium-yas composite tubesyog siv rau qhov no.

4. Kev hloov kho deg

Lub hom phiaj ntawm kev hloov kho qhov chaw yas tuaj yeem muab faib ua ob pawg: ib qho yog siv ncaj qha hloov kho, lwm qhov yog siv tsis ncaj rau kev hloov kho.

a.Kev hloov pauv ntawm cov khoom siv yas ncaj qha nrog rau qhov chaw gloss, deg hardness, nto hnav tsis kam thiab kev sib txhuam, nto tiv thaiv kev laus, nplaim taws retardant, nto conductivity thiab nto barrier, thiab lwm yam.

b.Kev siv tsis ncaj ntawm kev hloov pauv ntawm cov yas saum npoo suav nrog kev hloov kho los txhim kho qhov nro ntawm cov yas los ntawm kev txhim kho cov adhesion, printability thiab lamination ntawm plastics.Siv cov khoom siv electroplating ntawm cov yas ua piv txwv, tsuas yog txheej txheej ceev ntawm ABS tuaj yeem ua tau raws li qhov yuav tsum tau ua rau cov yas tsis muaj kev kho deg;Tshwj xeeb tshaj yog rau polyolefin plastics, txheej ceev yog tsawg heev.Kev hloov kho deg yuav tsum tau ua los txhim kho kev sib xyaw kom nrawm nrog cov txheej ua ntej electroplating.

Cov nram qab no yog ib txheej ntawm tag nrho ci ntsa iab nyiaj electroplated cov thawv kom hniav zoo nkauj: Ob phab ntsa 30g 50gcream thawv, 30 ml ntawm presseddropper lub raj misthiab 50 mllotion lub raj mis.
