Ungathuthukisa kanjani ukusebenza kokucubungula kwerabha ye-silicone enobulukhuni obuphansi?

1. Umthelela we-ejenti eqinisayo ekukhanyeni kwe-irabha ye-silicone

Njengoba zingekho izigcwalisi ku-MQ irabha eluhlaza, ukubukeka kwayo kuyingilazi futhi kusobala. Ngokwemiphumela yokuhlola, i-ejenti eqinisayo engu-0.3 phr cishe ayinawo umthelela ekukhanyeni kwejeli ye-silica, futhi isampula lisagcina izinga eliphezulu lokubonisa ngale. Uma inani elingeziwe likhushulwa libe ingxenye engu-1, ukubonakala kuncipha.


2. Umthelela we-ejenti eqinisayo ku-Mooney viscosity ye-MQ irabha eluhlaza

Ngokushintshwa kwe-Mooney viscosity yenjoloba, kungabonakala ukuthi ngemva kokwengeza i-ejenti eqinisayo, i-viscosity yenjoloba iyanda futhi amandla e-intermolecular ayanda, okuthuthukisa ukucutshungulwa kwejeli ye-silica.

Uma kuqhathaniswa ne-GS- 100, GS-101 ithuthukisa i-Mooney viscosity kahle kakhulu.

3. Ukuhlolwa kwe-ejenti eqinisayo ekusebenzeni kwe-MQ irabha eluhlaza

MQ irabha eluhlaza ngaphandle kwe-ejenti eqinisayo kunzima ukuyixuba emshinini ovulekile, irabha iphuka kalula, futhi akulula ukuyiginqa;

Ngemva kokwengeza 0.3phr i-ejenti eqinisayo, amandla aluhlaza we-MQ irabha eluhlaza athuthukisiwe, i-roller yesikhwama senjoloba ijwayelekile futhi umsebenzi wokudlula omncane ungenziwa;

Ngemva kokungeza i-ejenti eqinisayo engu-1.0phr, eluhlaza Amandla enhlanganisela yenjoloba ngokusobala athuthukisiwe, angcono nakakhulu kunokucubungula ukusebenza kwerabha ye-silicone enobulukhuni. Akukhona nje kuphela ukuthi ukuxuba kwerabha okujwayelekile kungenziwa kuphela, kodwa futhi nenani elikhulu lokugcwalisa lingagcwaliswa.


4. Izincomo zokusetshenziswa kwama-tougheners kujeli yesilika yobulukhuni obuphansi

Njengoba i-shear ye-intermolecular incane futhi izinga lokushisa lincane ngesikhathi sokuxutshwa kwejeli yesilika enobulukhuni obuphansi, kunconywa ukuthi izinga lokushisa lokuxutshwa lilawuleke phakathi kwamadigri angu-40 kanye Ama-degree angu-50, okungukuthi, ukwandisa ukuhlakazeka kwe-ejenti eqinisayo kujeli ye-silica, ukuthuthukisa umphumela wokuqina, futhi Okusiza ekunciphiseni isikhathi sokuhlanganisa. ukuqina kwejeli ye-silica, okwenza kube lula ukuthi inhlanganisela yenjoloba igoqe futhi ixutshwe.

Ngezinhlelo zokusebenza ezinezidingo ezibonakalayo eziphezulu, kunconywa ukulawula inani le-ejenti eqinisayo eyengezwe, ngo-0.3phr kube ehamba phambili.

Ngo imikhiqizo edinga ukwengeza inani elikhulu lama-fillers asebenzayo, njengemikhiqizo ene-conductivity kagesi ephezulu kanye ne-thermal conductivity ephezulu, kuhle ukwandisa inani le-ejenti eqinisayo eyengezwe ukuze kube lula ukugcwaliswa okuphezulu.

Uma kuqhathaniswa ne-GS-101, GS -101 inokusebenza okuphakeme okuphezulu ekuthuthukiseni amandla erabha eluhlaza, kuyilapho i-GS-100 inomphumela omncane ku-Mooney viscosity. Ilungele amafomula ane-money viscosity ephezulu kanye ne-extrusion enzima.

Compared with GS-101, GS-101 has a higher efficiency in improving the strength of raw rubber, while GS-100 has a smaller effect on Mooney viscosity. It is suitable for formulas with high Mooney viscosity and difficult extrusion.
