I-HPMC ku-dry powder mortar

I-hydroxypropyl methylcellulose ku-dry powder mortar, ukungezwa kwe-cellulose ether kuphansi kakhulu, kodwa kungathuthukisa kakhulu ukusebenza kwe-wet mortar, futhi kuyisengezo esiyinhloko esithinta ukusebenza kokwakhiwa kwe-mortar.

I-Hydroxypropyl methylcellulose I-cellulose ether esetshenziswa ku-dry powder mortar ikakhulukazi i-hydroxypropyl methylcellulose ether (HPMC). Ku-honeycomb ceramics entsha, inganikeza ukuthambisa endaweni engenalutho. Embonini yokumboza, ingasetshenziswa njengesithambisi, isihlakaza kanye nesiqinisi embonini yokumboza, futhi ihambisana kahle namanzi noma izinyibilikisi eziphilayo. Njengesisusa-pende. Ukuphrinta ngoyinki: Isetshenziswa njengesithambisi, isihlakaza kanye nesiqinisi embonini yeyinki, futhi ihambisana kahle namanzi noma izinyibilikisi eziphilayo. .Ipulasitiki: isetshenziswa njenge-ejenti yokukhulula, isithambisi, isithambisi, njll. I-Polyvinyl chloride: Isetshenziswa njengesithambisi ekukhiqizweni kwe-polyvinyl chloride, futhi iyi-ejenti eyinhloko yokusiza yokulungiselela i-PVC nge-suspension polymerization. I-Hydroxypropyl methylcellulose Okunye: Lo mkhiqizo usetshenziswa kabanzi nasezimbonini zesikhumba, zephepha, zokulondolozwa kwezithelo nemifino kanye nezendwangu.

I-HPMC ku-dry powder mortar idlala indima yokugcina amanzi, ukuqina kanye nokuthuthukisa ukusebenza kokwakha. Ukugcinwa kwamanzi okuphezulu ko-construction mortar kanye nesihlabathi sokuplasta kungamanzisa usimende ngokugcwele futhi kwandise kakhulu amandla okubopha. Ngesikhathi esifanayo, ingakhulisa ngokufanele amandla okubopha kanye namandla okugunda, ithuthukise kakhulu umphumela wokwakha futhi ithuthukise ukusebenza kahle komsebenzi. Imelana namanzi futhi inamafutha Ku-putty, i-hydroxypropyl methylcellulose cellulose ether idlala indima yokugcina amanzi, ukubopha kanye nokugcoba, igwema imifantu kanye nokuphelelwa amanzi okubangelwa ukulahlekelwa amanzi ngokweqile, futhi ngesikhathi esifanayo ithuthukisa ukunamathela kwe-putty futhi inciphise isikhathi sokwakha. Isenzakalo sokusa phakathi senza ukwakhiwa kube lula. Phakathi kwemikhiqizo yochungechunge lwe-gypsum, i-hydroxypropyl methylcellulose cellulose ether idlala indima yokugcina amanzi kanye nokugcoba, futhi ngesikhathi esifanayo inomphumela othile wokulibazisa, oxazulula izinkinga zokuqhekeka kwedrama kanye nokwehluleka kwamandla okuqala ngesikhathi sokwakha. , ingandisa amahora okusebenza. I-ejenti ye-interface ye-hydroxypropyl methylcellulose isetshenziswa kakhulu njengesithambisi, esingathuthukisa amandla okubopha kanye namandla okubopha, sithuthukise ukumbozwa kobuso, sithuthukise ukunamathela kanye namandla okubopha. Izakhiwo: Lo mkhiqizo uyimpuphu emhlophe noma ephuzi kancane, awunaphunga, awunambitheki futhi awunabo ubuthi. Ukugcinwa kwamanzi kanye namandla akhuphukile. , i-putty powder noma ezinye izinto zokwakha njenge-binder ukuthuthukisa ukusabalala nokwandisa isikhathi esisebenzayo. Ingasetshenziswa njengethayela lokunamathisela, imabula, umhlobiso wepulasitiki, ukuqinisa i-paste, futhi inganciphisa nenani lesimende. Ukusebenza kokugcina amanzi kwe-HPMC kuvimbela i-slurry ukuthi ingaqhekeki ngenxa yokomisa ngokushesha kakhulu ngemva kokusetshenziswa, futhi kuthuthukisa amandla ngemva kokuqina. Ukukhiqizwa kwe-ceramic: Isetshenziswa kabanzi njenge-binder ekwenziweni kwemikhiqizo ye-ceramic. Ukuqina kwe-PH: I-viscosity yesisombululo samanzi salo mkhiqizo izinzile ngokulingana ebangeni le-PH3.0-11.0. Umphumela wokugcinwa kwamanzi: I-Hydroxypropyl methylcellulose i-hydrophilic futhi isixazululo sayo samanzi siqinile kakhulu. I-Hydroxypropyl methylcellulose (HPMC) yengezwa ku-mortar, i-gypsum, upende, njll. ukuze kugcinwe ukugcinwa kwamanzi okuphezulu kumkhiqizo. Ukugcinwa komumo: Uma kuqhathaniswa namanye ama-polymer ancibilika emanzini, isixazululo samanzi salo mkhiqizo sinezakhiwo ezikhethekile ze-viscoelastic. Ukwengezwa kwaso kungathuthukisa ikhono lokuguquguquka komumo wemikhiqizo ye-ceramic ekhishwe, njll.

Ukugcotshwa kwe-hydroxypropyl methylcellulose (HPMC): Ukwengeza lo mkhiqizo kunganciphisa i-friction coefficient futhi kuthuthukise ukugcotshwa kwemikhiqizo ye-ceramic ekhishwe kanye nemikhiqizo yesamente. Izakhiwo zokwakha amafilimu: Lo mkhiqizo ungakhiqiza amashidi aqinile, aguquguqukayo, futhi asobala anokumelana okuhle kwamafutha kanye ne-ester, ikakhulukazi ukugcinwa kwamanzi kanye nokwakhiwa okuyingqayizivele kwe-hydroxypropyl methylcellulose (HPMC), i-hydroxypropyl methylcellulose Izakhiwo zokwakha amafilimu ze-cellulose bezilokhu ziphambili eShayina.
