1. Sibutsetelo
I-Hydroxypropyl Methyl Cellulose (HPMC) yi-ether ye-ether ye-moullerose engenzi kahle ye-polymer - cellulose ngokusebenzisa uchungechunge lwezinqubo zamakhemikhali. I-Hydroxypropyl Methylcellulose (HPMC) iyimpuphu ye-Lodorless, engenabutha, engachithwa emanzi abandayo ukwakha isixazululo esibonakalayo esibonakalayo, esinemisebenzi yokuqina, i-gelation, umsebenzi wokugcina, ukugcinwa komswakama kanye nokugcinwa komswakama kanye nokugcinwa komswakama kanye nokugcinwa komswakama kanye nezakhiwo zomswakama.
I-Hydroxypropyl Methylcellulose (HPMC) ingasetshenziswa ezintweni zokwakha, izimbobo, ama-desins zokwenziwa, ubumba - ubumba, umuthi, izimboni zezimo zikagwayi
2,Ukucaciswa komkhiqizo nemikhiqizo yokuhlukaniswa ihlukaniswe ngamanzi abandayo ancibilikayo s nohlobo olujwayelekile

3,Imvelo Yomkhiqizo
Izakhiwo: Lo mkhiqizo uwumpuphu omhlophe noma ongaphumeleli, ongenangelihle, awunambitha futhinon-atcic.
Ukulimazeka kwamanzi kanye nekhono lokuqina: Lo mkhiqizo ungachithwa emanzini abandayo ukwakha ikhambi elibonakalayo le-viscous.
Ukuchithwa ku-Organic Solvents: Ngoba iqukethe inani elithile lamaqembu we-hydrophobic methoxyl, lo mkhiqizo ungachithwa kwezinye izixazululo ze-organic, futhi futhi ungachithwa kuma-solvents ahlanganiswe namanzi nezinto eziphilayo.
Ukumelana nosawoti: Njengoba lo mkhiqizo uyi-polymer engeyona eye-ionic, kuzinzile ngezisombululo zama-aquous sosawoti wensimbi noma ama-opercrocytes aphilayo.
Umsebenzi ongaphezulu
I-Thermal Gelation: Lapho ikhambi elinamanzi alo mkhiqizo lifuthelwa amazinga okushisa athile, kuba yi-opaque kuze kube yilapho lakha isimo se-floccation, ukuze isixazululo) silahlekelwe ukubonakala kwaso. Kepha ngemuva kokupholisa, kuzophenduka isimo solukhuni sokuqala. Izinga lokushisa lapho kwenzeka khona ukubheja kuncike kuhlobo lomkhiqizo, ukugcwala kwesixazululo nesilinganiso sokushisa.
Ukuqina kwe-PH: I-Viscosity yesisombululo esinamanzi salo mkhiqizo sizinzile ngaphakathi kwe-PH3.0-11.0.
Umphumela wokugcina amanzi
Ukugcinwa kwe-Shape: Uma kuqhathaniswa namanye ama-polymers ancibilikayo amanzi, ikhambi elinamanzi alo mkhiqizo linezakhiwo ezikhethekile ze-viscoelastic. Isengezo sayo inamandla okugcina ukwakheka kwemikhiqizo ye-ceramic eyengeziwe engashintshiwe.
Ukugcoba: Ukungeza lo mkhiqizo kunganciphisa ukungqubuzana kokushayela izingxabano futhi kuthuthukise ukugcotshwa kwemikhiqizo ye-ceramic eyengeziwe nemikhiqizo yesimende.
Izakhiwo ezenziwe ngefilimu: Lo mkhiqizo ungakha ifilimu eguquguqukayo, esobala ngempahla enhle kakhulu yemishini, futhi inamafutha amahle nokuphikiswa kwamafutha
4. Izakhiwo Zomzimba Nezamakhemikhali
Ubukhulu bezinhlayiyana: Izinga lokuphasa le-100 Mesh likhulu kune-98.5%, isilinganiso esingu-80 sokuphasa se-Mesh yi-100%
Izinga lokushisa le-carbonization: 280 ~ 300 ℃
Ubuningi obubonakalayo: 0.25 ~ 0.70 / cm Amandla adonsela phansi athile adonsela phansi 1.26 ~ 1.31
Ukushisa kwe-Discoloration: 190 ~ 200 ℃
Ukungezwani komhlaba: 2% Isixazululo esinamanzi angama-42 ~ 56dyn / cm
I-Solubity: incibilika emanzini kanye nezinye izixazululo, ikhambi lamanzi elinomsebenzi ongaphezulu. Ukucaca okuphezulu. Ukusebenza okuzinzile, ushintsho lwe-solubal nge-viscosity, kwehlisa i-viscosity, kukhudlwana kukhulu.
I-HPMC nayo inezici zekhono lokuqina, ukumelana nosawoti, ukuqina kwe-PH, ukugcinwa kwamanzi, ukuqina okuyisisekelo, impahla ebabazekayo enhle yokumelana ne-enzyme, ukuhlukaniswa kanye nobumbano.
Ezinhlanu, inhloso eyinhloko
Ibanga le-Industrial Ibanga le-HPMC lisetshenziswa ikakhulukazi njenge-distrant ekukhiqizeni i-polyvinyl chloride, futhi i-ejenti ebalulekile yokulungiselela i-PVC ngokumiswa kwe-PVC ngokumiswa kwe-polymerization. Ngaphezu kwalokho, ingasetshenziswa njengesikhulu, i-Stabilizer, Emulsifier, Exelciant, kanye ne-ejenti yokugcina amanzi ekukhiqizeni amanye ama-petrochemicals, ama-cosmetics, i-ejenti, i-teatile, i-ejenti, njll. Isicelo, i-Agents, i-Agents e-Agents, njll. Izinhlayiya ezikhuluphele, amandla adonsela phansi afanele kanye nokusebenza okuhle kakhulu kokusebenza, ngakho-ke ngokuyisisekelo kuthatha indawo ye-gelatin kanye ne-polyvinyl utshwala njengabahlakazekile.
Izindlela eziyisithupha zokuqothula:
(1). Thatha inani elidingekayo lamanzi ashisayo, ulifake esitsheni bese usishisa ngenhla kwama-80 ° C, bese kancane kancane engeza lo mkhiqizo ngaphansi kokushukumisa kancane. I-cellulose intanta endaweni yamanzi ekuqaleni, kepha kancane kancane ihlakazeka ukuze kwakhiwe i-slurry efanayo. Isixazululo saphola ngenkathi sivusa.
(2). Ngenye indlela, ukushisa okungu-1/3 noma 2/3 kwamanzi ashisayo kungaphezulu kwama-85 ° C, engeza i-cellulose ukuthola i-slurry yamanzi eshisayo, bese ufaka inani elisele lamanzi abandayo, hlala uvuse, futhi upholise inhlanganisela ephumayo.
(3). I-meshele ye-cellulose ilungile, futhi ikhona njengezinhlayiya ezithile ezincane ku-powder eshukumisayo, futhi iyancibilika ngokushesha lapho ihlangana namanzi ukuze yakhe ukubonakala okudingekayo.
(4). Kancane kancane futhi ngokulinganayo engeza iselula lokushisa kwekamelo, kuvuse ngokuqhubekayo kuze kube kwakhiwa isixazululo esibonakalayo.
