Yuav ua li cas txo tus nqi ntawm cov roj hmab compounding

Nyob rau hauv lub ntiaj teb kev sib tw siab heev ntawm kev lag luam roj hmab, tus nqi ntawm kev sib xyaw ua ke yog qhov tseem ceeb rau kev lag luam zoo ntawm cov khoom lag luam. Nws muaj peev xwm tsim ib qho kev sib xyaw ua ke uas ua tau raws li cov neeg siv khoom xav tau ntawm ob qho tib si kev ua tau zoo, tab sis raug tsis lees paub los ntawm cov neeg siv khoom vim nws kim heev.

Tsis tas li ntawd, cov khoom siv roj hmab feem ntau yog muag los ntawm ntim ntau dua li qhov hnyav (cov khoom pwm feem ntau yog qhov loj). Yog li ntawd, nws ua rau kev txiav txim siab los piv qhov 'tus nqi ib ntim' es tsis yog 'tus nqi ib qhov hnyav' ntawm roj hmab.

Cov xwm txheej hauv qab no tuaj yeem txo tus nqi kev lag luam ntawm qhov sib xyaw. Nco tseg: Cov xwm txheej kev sim dav dav no yuav tsis siv tau rau txhua kis tshwj xeeb. Ib qho kev hloov pauv uas txo tus nqi yuav cuam tshuam rau lwm yam khoom, kom zoo dua lossis phem dua.

1. Carbon dub/plasticizer

Xaiv cov qauv zoo carbon dub thiab siv cov roj muab tub lim siab yuav ua rau cov qauv ntawm cov khoom sib txuas tsis tu ncua thaum tus nqi qis.

2. Carbon dub filling npaum li cas

Xav txog kev xaiv cov qauv uas tsis tshua muaj thiab tsis tshua muaj qhov tshwj xeeb ntawm cov pa roj carbon dub, vim tias cov pa roj carbon dub no tsis yog pheej yig dua, tab sis kuj muaj cov nyiaj ntim ntau, uas tuaj yeem txo cov nqi roj hmab zoo.

Xaiv ultra-low structured semi-reinforced carbon dub, vim nws tuaj yeem ua kom muaj ntau, uas tuaj yeem txo cov nqi roj hmab zoo.

Xaiv qhov chaw tshwj xeeb qis thiab cov txheej txheem qis carbon dub los sau cov roj hmab uas muaj nqi siab, thiab khaws cov viscosity ntawm cov roj hmab tsis siab dhau, kom cov roj hmab tuaj yeem txhaj tshuaj molded lossis vulcanized los ntawm lwm txoj kev, thiab tus nqi yuav raug txo qis.

3. Silica

Rau qhov qis dov tsis kam thiab kev ua haujlwm tsis zoo, silica feem ntau yog siv los ua tus muab tub lim thiab siv cov organosilane coupling agent. Silane coupling agents yog kim, thiab yog hais tias ib tug me me npaum li cas ntawm silane coupling tus neeg sawv cev yuav siv tau thiab kev ua tau zoo ntawm cov compound tseem tsis hloov, tus nqi ntawm cov compound yuav txo tau heev. Ib qho kev coj ua yog siv silica nrog cov ntsiab lus siab ntawm hydroxyl, raws li nws tau kawm los ua ke yooj yim dua. Yog li, nrog ntau pawg hydroxyl nyob rau hauv cov compound, tsawg silane coupling tus neeg sawv cev yog xav tau thiab tib yam khoom siv tau khaws cia thaum tus nqi txo.

4. Filler

Nyob rau hauv TIO2-filled dawb compounds, lwm yam uas tsis muaj nqi dawb fillers (xws li dej-ntxuav av nplaum, calcium carbonate, whitening agent, thiab lwm yam) tuaj yeem txiav txim siab los hloov qee qhov TIO2, thiab cov compound tseem yuav muaj peev xwm npog thiab dawb.

Nyob rau hauv silica tread compounds, hloov qee cov silica nrog carbon dub-silica biphasic fillers tuaj yeem txo tus nqi ntawm cov khoom sib xyaw, vim tias nws tuaj yeem txo tus nqi ntawm silane coupling tus neeg sawv cev, thiab tseem txo cov qib kev kho cua sov hauv cov txheej txheem sib tov.

Sau cov roj hmab nrog calcium carbonate yuav txo tus nqi ntawm cov roj hmab. Ib yam li ntawd, av nplaum yuav txo tau tus nqi ntawm cov nplaum.

Txawm hais tias qhov ceev ntawm talc (2.7g / cm3) yog ntau dua li cov pa roj carbon dub (1.8g / cm3), yog tias 1.5 qhov chaw (los ntawm huab hwm coj) ntawm talc siv 1 feem (los ntawm huab hwm coj) ntawm cov pa roj carbon dub, tus nqi ntawm cov compound tuaj yeem raug txo. Tsis tas li ntawd, talc hmoov yuav ua rau kom lub extrusion ceev thiab txhim kho cov zis, uas yuav indirectly txo tus nqi.

5. Kev txo qis

Cov khoom siv roj hmab feem ntau raug nqi los ntawm ntim ntau dua li qhov hnyav. If you change the rubber formula to make the density lower, while keeping the price per unit volume unchanged, then you can indirectly reduce the cost. Piv txwv li, los ntawm kev hloov CR nrog NBR, tus nqi ntawm ib chav tsev ntim ntawm cov roj hmab tee, yog tias lwm cov kev hloov pauv hauv cov roj hmab tsis cuam tshuam qhov txiaj ntsig ntawm cov nqi no.

6. tau hloov ob-kauj ruam compounding nrog additive compounding.

Yog tias ua tau, hloov ob-kauj ruam kev sib xyaw nrog ib-kauj ruam sib xyaw los ntawm cov txheej txheem tswj hluav taws xob thiab cov txheej txheem kev ntsuas hluav taws xob zoo tuaj yeem txo cov nqi.

7. Kev pab ua haujlwm

Kev siv cov khoom siv tuaj yeem txhim kho qhov extrusion lossis calendering ceev ntawm cov khoom sib xyaw, yog li txo cov nqi.

8. FKM/ACM sib xyaw

Hloov cov ntshiab FKM nrog peroxide-kho FKM / ACM blend (Dai-El AG-1530) tuaj yeem ua rau cov roj hmab muaj cua sov thiab roj zoo dua.
