Txhua yam uas tuaj yeem txhim kho cov khoom qub ntawm cov resin los ntawm kev cuam tshuam lub cev, tshuab thiab tshuaj lom neeg tuaj yeem hu uakev hloov kho yasLub ntsiab lus ntawm kev hloov kho yas yog dav heev. Thaum lub sijhawm hloov kho, ob qho kev hloov pauv lub cev thiab tshuaj lom neeg tuaj yeem ua tiav nws.
Cov txheej txheem siv rau kev hloov kho yas yog raws li nram no:
1. Ntxiv cov tshuaj hloov kho
a. Ntxiv cov khoom me me uas tsis muaj organic lossis organic
Cov khoom siv inorganic xws li cov khoom sau, cov neeg sawv cev txhawb zog, cov tshuaj tiv thaiv hluav taws, cov xim thiab cov neeg sawv cev nucleating, thiab lwm yam.
Cov khoom ntxiv rau cov organic suav nrog cov yas ua kom cov yas, cov tshuaj organotin stabilizers, cov tshuaj antioxidants thiab cov tshuaj tua hluav taws xob, Cov khoom ntxiv rau kev puas tsuaj, thiab lwm yam. Piv txwv li, Topfeel ntxiv cov khoom ntxiv uas tuaj yeem puas tsuaj rau qee lub raj mis PET kom ua kom nrawm dua qhov kev puas tsuaj thiab kev puas tsuaj ntawm cov yas.
b. Ntxiv cov tshuaj polymer
2. Kev hloov kho cov duab thiab cov qauv
Txoj kev no feem ntau yog tsom rau kev hloov kho cov qauv thiab cov qauv ntawm cov yas nws tus kheej. Txoj kev ib txwm yog hloov pauv lub xeev siv lead ua ntawm cov yas, crosslinking, copolymerization, grafting thiab lwm yam. Piv txwv li, styrene-butadiene graft copolymer txhim kho qhov cuam tshuam ntawm cov khoom siv PS. PS feem ntau siv rau hauv cov khoom siv TV, cov khoom siv hluav taws xob, cov cwj mem ballpoint, cov teeb thiab cov tub yees, thiab lwm yam.
3. Kev hloov kho sib xyaw
Kev hloov kho cov yas sib xyaw yog ib txoj kev uas ob lossis ntau txheej ntawm cov yeeb yaj kiab, cov ntawv thiab lwm yam khoom siv tau sib xyaw ua ke los ntawm kev nplaum lossis kub yaj los ua cov yeeb yaj kiab ntau txheej, daim ntawv thiab lwm yam khoom siv. Hauv kev lag luam ntim khoom kom zoo nkauj, cov raj yas kom zoo nkauj thiabcov raj yas sib xyaw ua ke txhuassiv rau hauv qhov no.
4. Kev hloov kho qhov chaw
Lub hom phiaj ntawm kev hloov kho yas nto tuaj yeem muab faib ua ob pawg: ib qho yog kev hloov kho ncaj qha, qhov thib ob yog kev hloov kho tsis ncaj qha.
a. Kev hloov kho yas ncaj qha rau ntawm qhov chaw xws li kev ci ntsa iab ntawm qhov chaw, qhov tawv ntawm qhov chaw, kev tiv thaiv kev hnav thiab kev sib txhuam ntawm qhov chaw, kev tiv thaiv kev laus ntawm qhov chaw, kev tiv thaiv hluav taws ntawm qhov chaw, kev coj ua hluav taws xob ntawm qhov chaw thiab kev thaiv ntawm qhov chaw, thiab lwm yam.
b. Kev siv tsis ncaj qha ntawm kev hloov kho qhov chaw yas suav nrog kev hloov kho kom txhim kho qhov nro ntawm cov yas los ntawm kev txhim kho qhov lo, kev luam tawm thiab kev lamination ntawm cov yas. Piv txwv li, siv electroplating kho kom zoo nkauj rau ntawm cov yas, tsuas yog qhov ceev ntawm ABS thiaj li ua tau raws li qhov yuav tsum tau ua rau cov yas tsis muaj kev kho qhov chaw; Tshwj xeeb tshaj yog rau polyolefin yas, qhov ceev ntawm txheej yog qis heev. Kev hloov kho qhov chaw yuav tsum tau ua kom txhim kho qhov ceev ntawm kev sib xyaw ua ke nrog txheej ua ntej electroplating.
Cov hauv qab no yog cov thawv ntim khoom siv pleev ib ce uas ci ntsa iab thiab muaj nyiaj electroplated: Ob chav phab ntsa 30g 50glub thawv tshuaj pleev ib ce, 30ml niaslub raj mis dejthiab 50mllub raj mis tshuaj pleev ib ce.
