Zinthu Zomwe Zimakhudza Kuyera kwa Hydroxypropyl Methyl Cellulose

Kuyera kwa hydroxypropyl methylcellulose mu mortar yoteteza nyumba ndi ufa wa putty kumakhudza mwachindunji ubwino wa zomangamanga, ndiye ndi zinthu ziti zomwe zimakhudza kuyera kwa hydroxypropyl methylcellulose? Ndiloleni ndikuyankheni funso ili.

Pakupanga hydroxypropyl methylcellulose, mpweya wotsalira mu reactor udzayambitsa kuwonongeka kwa hydroxypropyl methylcellulose ndikuchepetsa kulemera kwa mamolekyulu, koma mpweya wotsalirawo ndi wochepa, bola ngati sikovuta kwambiri kulumikizanso mamolekyu osweka. Kuchuluka kwa madzi kofunikira kwambiri kumakhudzana kwambiri ndi kuchuluka kwa hydroxypropyl. Mafakitale ena amangofuna kuchepetsa mtengo ndi mtengo, koma safuna kuwonjezera kuchuluka kwa hydroxypropyl, kotero mtundu wake sungafikire pamlingo wa zinthu zofanana zakunja.

Kuchuluka kwa madzi omwe amasungidwa mu hydroxypropyl methylcellulose kumagwirizananso kwambiri ndi hydroxypropyl, ndipo pa njira yonse yochitira zinthu, hydroxypropyl imatsimikiziranso kuchuluka kwa madzi omwe amasungidwa mu hydroxypropyl methylcellulose. Zotsatira za alkaliization, chiŵerengero cha methyl chloride ndi propylene oxide, kuchuluka kwa alkali ndi chiŵerengero cha madzi ndi thonje loyengedwa zonse zimatsimikizira magwiridwe antchito a chinthucho.

Ubwino wa zipangizo zopangira, zotsatira za alkalizing, kuwongolera chiŵerengero cha njira, chiŵerengero cha zosungunulira ndi zotsatira za neutralization zonse zimatsimikizira ubwino wa hydroxypropyl methylcellulose, ndipo hydroxypropyl methylcellulose ina imapangidwa kuti isungunuke Pambuyo pake, inali mitambo ngati kuwonjezera mkaka, ina inali yoyera ngati mkaka, ina inali yachikasu, ndipo ina inali yowonekera bwino komanso yowonekera. Ngati mukufuna kuthetsa vutoli, sinthani kuchokera pa mfundo zomwe zili pamwambapa. Nthawi zina acetic acid ingakhudze kwambiri kutumiza kwa kuwala. Ndi bwino kugwiritsa ntchito acetic acid mutasungunuka. Chisonkhezero chachikulu ndichakuti ngati zomwe zimachitikazo zasunthidwa mofanana komanso ngati chiŵerengero cha dongosolo chili chokhazikika (zipangizo zina zimakhala ndi chinyezi ndipo zomwe zili mkati mwake sizikhazikika, monga zosungunulira zobwezeretsanso). Ndipotu, pali zinthu zambiri zomwe zikugwiritsidwa ntchito. Ndi kukhazikika kwa zida ndi magwiridwe antchito a ogwira ntchito ophunzitsidwa bwino, zinthu zomwe zimapangidwa ziyenera kukhala zokhazikika kwambiri. Kutumiza kwa kuwala sikudzapitirira ±2%, ndipo kufanana kwa magulu osinthira kuyenera kulamulidwa bwino. M'malo mofanana, kutumiza kwa kuwala kungakhale bwino.
