Hordhac Hydroxypropyl Methyl Cellulose
Hydroxypropyl methylcellulose, oo sidoo kale loo yaqaan hypromellose iyo HPMC cellulose hydroxypropyl methyl ether, waxay ka samaysan tahay cellulose suuf ah oo aad u saafi ah sida walxo ceeriin ah, taas oo si gaar ah loogu nadiifiyo xaaladaha alkaline.HPMC waa budo cad, aan dhadhamin, ur lahayn, aan sun ahayn, gebi ahaanba aan isbeddelin jidhka bini'aadamka oo laga soo saaro jidhka.Alaabtu waxay ku milmi kartaa biyaha, laakiin kuma milmi karaan biyaha kulul.Xalka aqueous waa walax hufan oo hufan oo aan midab lahayn.HPMC waxay leedahay dhumuc aad u fiican, emulsifying, film-samaynta, kala firdhiyey, kolloid ilaalinta, haynta qoyaanka, adhesion, acid iyo iska caabin alkali, caabbinta enzyme iyo guryaha kale, waxaana si ballaaran loo isticmaalaa in dhismaha, daahan, daawo, cuntada, dunta, beeraha saliidda. waxyaalaha la isku qurxiyo, Wakiilada dhaqida, ceramics, khadadka iyo hababka polymerization kiimikaad.
1. Kaalshiyam yar oo kalsiyum cawl ah iyo saamiga aan habboonayn ee CaO iyo Ca(OH)2 ee kaalshiyam cawl waxay sababi doontaa luminta budada.Haddii ay wax ku leedahay HPMC, markaa haddii haynta biyaha ee HPMC ay liidato, waxay sidoo kale sababi doontaa luminta budada.Luminta budada budada ah ma la xiriirta hydroxypropyl methylcellulose?Luminta budada budada ah waxay inta badan la xiriirta tayada kaalshiyamka dambaska, wax yarna kuma laha HPMC.
2. Shaqada ugu muhiimsan ee hydroxypropyl methylcellulose waa haynta biyaha, oo ay ku xigto dhumucdi.In budada putty, ilaa iyo inta haynta biyuhu ay wanaagsan yihiin iyo viscosity hooseeyo (70,000-80,000), sidoo kale waa suurtogal.Dabcan, mar kasta oo viscosity-ku sarreeyo, ayaa si fiican u sii haynta biyaha.Marka viscosityku ka bato 100,000, majiishu waxay saamayn doontaa haynta biyaha.Wax badan maaha.
Waa maxay viscosity ee hydroxypropyl methylcellulose (HPMC)?
Budada Putty guud ahaan waa 100,000 yuan, shuruudaha hoobiye ayaa ka sarreeya, 150,000 yuan ayaa loo baahan yahay si sahlan loo isticmaalo.
3. Waa maxay alaabta ceeriin ee ugu muhiimsan ee hydroxypropyl methylcellulose?Waxyaabaha ugu muhiimsan ee ceeriin ee hydroxypropyl methylcellulose (HPMC): suuf la safeeyey, methyl chloride, propylene oxide, iyo alaabta kale ee ceeriin, soodhaha caustic, acid, Toluene, isopropanol, iwm.
4. Waa maxay sababta urta hydroxypropyl methylcellulose?Hydroxypropyl methylcellulose ee ay soo saarto habka dareeraha ayaa isticmaala toluene iyo isopropanol sida dareerayaasha.Haddii maydhisku aanu aad u fiicnayn, waxa jiri doona xoogaa ur ah .
5. Hydroxypropyl methylcellulose: Midka leh maadada hydroxypropyl sare ayaa guud ahaan ku fiican xajinta biyaha.Midka leh viscosity sare wuxuu leeyahay haynta biyaha ka wanaagsan, xad (aan gabi ahaanba ahayn), iyo kan leh mawjadaha sare ayaa si fiican loogu isticmaalaa hoobiye sibidhka.Waa maxay tilmaamayaasha ugu muhiimsan ee farsamada?Waxyaabaha ku jira Hydroxypropyl iyo viscosity, isticmaalayaasha badankoodu waxay ka walaacsan yihiin labadan tilmaame.
Dhacdada efflorescence ee hoobiye miyay xiriir la leedahay hydroxypropyl methylcellulose?
Waqti ka hor, macaamiil ayaa sheegay in alaabtu leedahay efflorescence, oo uu samaynayo buufin.Shotcrete: Shaqada ugu weyn waa in la daboolo dhabarka, qallafsanaan, iyo kordhinta ku dheggan u dhexeeya gidaarka iyo walxaha dusha sare.Isticmaal wax yar, kaliya ku buufi lakab khafiif ah derbiga.Halkan waxaa ah sawirka ifafaalaha efflorescence ee macmiilku ii soo diray: Sawirka falcelintayda ugu horreysa ayaa ah in aysan hubaal ahayn sababta hydroxypropyl methylcellulose, sababtoo ah hydroxypropyl methylcellulose ma aha mid ku habboon wax kasta oo ka mid ah baaruuddu ka falcelisay.Iyo ifafaalaha efflorescence waa: shubka caadiga ah waa silicate, marka uu la kulmo hawada ama qoyaanka gidaarka, ion silicate wuxuu ku dhacaa falcelin hydrolysis ah, iyo hydroxide-ku-abuuray wuxuu ku daraa ions birta si ay u sameeyaan hydroxide leh milmay hoose (qalabka kiimikada Alkaline). , marka heerkulku kordho, uumiga biyuhu wuu uumi baxaa, hydroxide-kuna waxa uu ka soo degdegaa gidaarka.Biyaha si tartiib tartiib ah u soo baxayo, hydroxide-ku wuxuu ku soo degdegayaa dusha sibidhka shubka ah, kaas oo ku urura waqti ka dib, samaynta qurxinta asalka ah Marka rinjiga ama rinjiga kor loo qaado oo aan mar dambe ku dhejin derbiga, caddeynta, diirinta, iyo diirka ayaa dhacaya.Habkaan waxaa loo yaqaan "pan-alkali".Markaa ma aha ubiquinol-ka ay keento hydroxypropyl methylcellulose
Macmiilku waxa kale oo uu xusay dhacdo: grout buufin ah oo uu sameeyey waxay yeelan doontaa ifafaale pan-alkaline ah derbiga shubka ah, laakiin ma ka muuqan doono derbiga leben la shiday, taas oo muujinaysa in silikoon ee sibidhka loo isticmaalo on derbiga shubka ah Salts (xoog alkaline). cusbada) aad bay u badan tahay.Efflorescence ay keento uumiga biyaha loo isticmaalo grouting buufinta.Si kastaba ha ahaatee, ma jiraan wax silicate ah oo ku yaal gidaarka lebenka ah ee la eryay mana dhici doonto wax soo jiidasho leh.Markaa ifafaalaha efflorescence waxba kuma laha buufinta.
Xalka:
1. Maaddada silicate ee sibidhka aasaasiga ah waa la dhimay.
2. Isticmaal wakiilka dahaarka dambe ee anti-alkali, xalku waxa uu galaa dhagaxa si uu u xidho xididada, si biyaha, Ca (OH) 2, milix iyo walxaha kale ma dhex gelin karaan, oo gooyay habka pan-alkaline ifafaale.
3. Kahortagga soo galinta biyaha, hana rushaynin biyo badan ka hor dhismaha.
Daawaynta ifafaale pan-alkaline:
Wakiilka nadiifinta efflorescence dhagaxa ee suuqa waa la isticmaali karaa.Wakiilkan nadiifinta ah waa dareere aan midab lahayn oo ka samaysan surfactants iyo dareere aan midab lahayn.Waxay saameyn gaar ah ku leedahay nadiifinta dhagaxyada dabiiciga ah qaarkood.Laakin ka hor intaanad isticmaalin, hubso inaad samaysato qayb yar oo tijaabo ah si aad u tijaabiso saamaynta una go'aansato inaad isticmaasho iyo in kale.
