Eyona HPMC yoShishino Gypsum

I-HPMC, okanye i-Hydroxypropyl Methyl Cellulose, iqhele ukusetyenziswa njenge-thickener, i-binder kunye nefilimu yangaphambili kumashishini ahlukeneyo, kuquka ukwakhiwa. Ukusetyenziswa kwe-powder ye-gypsum yoshishino, njenge-plasters-based plasters, iikhompawundi ezidibeneyo okanye i-dry-mix mortars, ukukhetha ibakala elifanelekileyo le-HPMC kubalulekile ekufezekiseni umsebenzi ofunekayo kunye neempawu zemveliso.

Nazi ezinye izinto ekufuneka ziqwalaselwe xa ukhetha eyona HPMC ilungileyo kwigypsum yoshishino:

I-Viscosity: I-viscosity ye-HPMC imisela ukugcinwa kwayo kwamanzi kunye neempawu zokuqina. Kwizicelo ezisekelwe kwi-gypsum, amabakala aphakathi ukuya kwi-viscosity aphezulu e-HPMC adla ngokukhethwa ukubonelela ngokuqhubekeka kakuhle kunye nokuxhathisa kwe-sag. Amanqaku aqhelekileyo e-viscosity ye-industrial gypsum powders avela kwi-4,000 ukuya kwi-100,000 cP (centipoise).

Ukugcinwa kwamanzi: I-HPMC inceda ukugcina amanzi kumxube, okuvumela ukuba i-hydration engcono yamasuntswana e-gypsum kunye nokusebenza okuphuculweyo. Iimveliso ezisekelwe kwi-Gypsum zifuna ukugcinwa kwamanzi okuphezulu ukuthintela ukomisa ngokukhawuleza kunye nokuqhekeka. Jonga amabanga e-HPMC eyilelwe ngokukodwa ugcino lwamanzi olwandisiweyo.

Ukubeka Ulawulo Lwexesha: I-HPMC ichaphazela ixesha lokumisela iimveliso ezisekelwe kwi-gypsum. Kuxhomekeke kwisicelo, unokufuna ibakala le-HPMC elibonelela ngexesha elithile elibekiweyo. Abavelisi badla ngokubonelela ngolwazi malunga nefuthe lamabakala abo e-HPMC ekubekeni ixesha ukuze ukwazi ukukhetha eyona ifanele iimfuno zakho.

Ukuhambelana: Qinisekisa ukuba ibakala le-HPMC olikhethayo liyahambelana negypsum kunye nezinye izithako ekuqulunqweni kwakho. Kufuneka isasazeke ngokulula kwaye ngokulinganayo kumxube ngaphandle kokubangela nayiphi na impendulo embi okanye ichaphazela iimpawu zemveliso yokugqibela.

Umgangatho kunye nomthombo: Khetha umboneleli we-HPMC owaziwa ngokuvelisa iimveliso ezikumgangatho ophezulu. Abavelisi abathembekileyo babonelela ngomgangatho we-HPMC ongaguqukiyo, obaluleke kakhulu kwi-batch-to-batch consistency kwimveliso yamashishini.

Khumbula ukuvavanya ibakala elikhethiweyo le-HPMC kulingo oluncinci ukuze uqinisekise ukuba liyahlangabezana neemfuno zakho zokusebenza phambi kokufudukela kwimveliso enkulu.
