Cellulose ether series khoom los ntawm Shandong Sparrow Chemical CO., LTD
Roj & roj drilling
Siv rau hauv cov kua ua tiav
Roj thiab roj txheej tiv thaiv: CMC hauv cov kua ua tiav tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm phab ntsa zoo thiab qhov chaw ntawm cov roj thiab cov roj txheej los tiv thaiv cov dej drilling thiab lwm yam dej txawv teb chaws los ntawm kev ua kom cov roj thiab roj txheej thaum ua tiav, xws li av nplaum o thiab particle tsiv teb tsaws, thiaj li tiv thaiv cov permeability thiab productivity ntawm cov roj thiab roj txheej thiab txhim kho cov roj thiab roj zoo.
Stabilizing lub qhov dej: Thaum lub sijhawm ua tiav, lub qhov dej yuav tsum tau ua kom ruaj khov kom ntseeg tau tias muaj kev nyab xeeb thiab du ntawm kev ua haujlwm tom ntej. CMC tuaj yeem kho qhov ua tiav ntawm cov kua ua tiav kom muaj qhov zoo viscosity thiab pom cov khoom, uas tuaj yeem pab tswj kom muaj qhov sib npaug ntawm cov phab ntsa zoo thiab tiv thaiv kom tsis txhob tawg lossis tawg ntawm phab ntsa zoo.
Tus neeg nqa tshuaj
Excipients rau cov ntsiav tshuaj thiab tshuaj ntsiav
Adhesive: CMC tuaj yeem siv los ua cov nplaum hauv cov ntsiav tshuaj. Nws tuaj yeem txuas cov tshuaj hmoov hmoov ua ke, kom cov ntsiav tshuaj muaj qee qhov hardness thiab lub zog, thiab yooj yim rau kev tsim thiab thauj. Nyob rau tib lub sijhawm, nws cov dej zoo solubility pab txhawb kev tawg sai ntawm cov ntsiav tshuaj hauv plab hnyuv, tso cov tshuaj, yog li ua kom cov bioavailability ntawm cov tshuaj.
Disintegrant: CMC tuaj yeem siv los ua cov tshuaj tsis sib xws hauv cov tshuaj ntsiav. Thaum cov tshuaj ntsiav nkag mus rau hauv txoj hnyuv, CMC tuaj yeem nqus dej sai thiab o, uas ua rau lub plhaub capsule tawg thiab txhawb kev tso tawm cov tshuaj. Piv nrog rau lwm cov disintegrants, cov nyhuv disintegration ntawm CMC yog me me thiab tsis cuam tshuam rau kev ruaj ntseg thiab tso tus cwj pwm ntawm cov tshuaj.
Thickener
Tshuaj txhuam hniav: Ntxiv CMC hauv cov tshuaj txhuam hniav tuaj yeem kho qhov sib xws ntawm cov tshuaj txhuam hniav, ua kom nws muaj qhov zoo extrusion thiab molding, tab sis kuj tuaj yeem txhim kho kev ruaj ntseg ntawm cov tshuaj txhuam hniav, tiv thaiv cov khoom xyaw hauv cov tshuaj txhuam hniav los ntawm kev sib cais los yog precipitating thaum lub sij hawm cia.
Kev npaj ua kua: Hauv kev npaj ua kua xws li cov kua hauv qhov ncauj thiab tshem tawm, CMC ua tus neeg sawv cev thickening tuaj yeem ua kom cov viscosity ntawm cov kua, ua kom cov tshuaj sib npaug sib npaug hauv cov tshuaj, tiv thaiv cov tshuaj los nag, thiab tseem txhim kho cov saj ntawm cov tshuaj rau cov neeg mob noj.
Haus dej: Ntxiv CMC hauv cov kua txiv hmab txiv ntoo, tshuaj yej dej haus, dej haus protein, thiab lwm yam, tuaj yeem ua kom cov viscosity ntawm cov dej haus, txhim kho saj, thiab ua kom nws zoo dua smoothness thiab fullness. Nyob rau tib lub sijhawm, nws tseem tuaj yeem tiv thaiv cov khoom xyaw hauv cov dej haus los ntawm nag lossis daus los yog delamination, txhim kho kev ruaj ntseg ntawm cov khoom.
