Waa maxay macnaha ugu weyn ee ceeriin ugu weyn ee hydroxypropyl methylrcellulose

Qalabka ugu weyn ee cayriin ee HPMC waa sidii wax kale:

Lagu safeeyey suufka, methyl chloride, propylene oxide, ashyaa'da ceyriinka ah, caustic soodhada, aashitada, toluene, isopripanol, iwm.

Waa maxay saamaynta ugu muhiimsan ee hydroxypropyl methylrcellulose budada isbeddelka, iyo ha ahaato in kimisato dabiici ah ay dhacdo?

HPMC waxay ciyaareysaa seddex howlood oo ka mid ah dhumucda, haynta biyaha iyo dhismaha budada wareega.

Qulqulka: methylcellelose waxaa lagu urursan karaa sabuurad, xalal aqueous ah si loo ilaaliyo labis iyo shaqo joogto ah oo looga hortago qulqulka.

Haynta biyaha: budada darbiga gudaha ah si tartiib tartiib ah ayey u qallajisaa, oo lime kaalshiyamka ah ayaa lagu daray in lagu muujiyo biyaha.

Dhismaha Injineerinka: Midaynta methyl wuxuu leeyahay saameyn saliibaad ah, kaas oo ka dhigi kara budada is-beddelka leh qaab-dhismeedka injineernimada wanaagsan. HPMC kuma lug laha dhammaan isbeddelada kiimikada laakiin kaliya ayaa lagu kabo. Budada wareega, derbiga, waa isbedel kiimiko ah, maxaa yeelay waxaa jira isbadal cusub oo kiimiko ah, budada wareega ayaa ka soo baxa derbiga, oo ay dib u qaadaan walax kiimikaad oo cusub (Kalsium Carbochote) ayaa la soo saaray. Waxyaabaha ugu waaweyn ee dambas kaalshiyamka ah ee kaalshiyamka ah waa: CA (Oh) 2, CAO iyo qadar yar oo ka mid ah xeryo3-CAOh) 2cacoca (OH), halka MPC kaliya ay tahay mid kalkaali joog u ah casharka, taas oo lafteedu ka qeybgalin wax ka turjuma.

Muxuu u adeegsanayaa daadashada aqal-hoosaadka hyroxypropyl methylcelrelose, oo muxuu qabtaa hydroxypropylcellosure ku jira budada wareega, oo aad u wanaagsan jahwareerka sibidhka iyo xabagta. haynta biyaha iyo isku-darka. Waxay leedahay qoyaan wanaagsan, kala firidhsan, isku-darka, qaro, qaro, emulsition, emulsific, biyo-haynta iyo astaamaha sameynta, iyo lacag-dheereynta saliida. Danzhai Hydroxypropylvyl menulus melulose wuxuu bixiyaa tiro badan oo kala firidhsan iyo xasilinta. Ionic cmc waxaa badanaa loo isticmaalaa isbadal saabuunta wasakhda ah. Sidoo kale si ballaaran loogu adeegsaday resin isku-dhafan, patroochemical, dhoobada, waraaqda, maqaarka, maqaarka iyo warshadaha cosmetics.
