Kugumana amazi ya hydroxypropyl methylcellse ether
Kugumana amazi yo kwizihiza minisiteri bivuga ubushobozi bwa minisiteri gufata no gufunga amazi. Hejuru ya virusi ya hydroxyproppopyl methylcellse ether, icyubahiro cyiza. Kuberako imiterere ya selile irimo hydroxyl na ether inyobe za ogisijeni ku matsinda ya ogisijeni ahuza na molekile y'amazi, bityo amazi yubusa ahinduka amazi, bityo akagira uruhare mu mazi, bityo amazi meza, bityo akagira uruhare mu mazi, bityo akagira uruhare mu ihohoterwa rishingiye ku mazi.
Kukesha kwishura hydroxypropyl methyl selile
1. Ububiko bwa Cearse ether biroroshye gutatana mumazi adahuye, ariko igipimo cyo gusebanya kiratinda cyane. Cellulose ether munsi ya metero 60 ishonga mumazi muminota 60.
2. Ububiko bwiza bwa selile biroroshye gutatana mumazi nta bagGuration, kandi igipimo cyo gusebanya kiringaniye. Cekwil ether hejuru ya metero 80 ishonga mumazi muminota 3.
3. Ultra-Pliple Fliverle iratatanye vuba mumazi, irashonga vuba, kandi ikora visositily. Ubugari bwa selile hejuru ya metero 120 irashonga mumazi kumasegonda 10-30.
Ibice byiza bya hydroxyproppopyl methylcellse ether, nibyiza kugumana amazi. Ubuso bwa selile yatunganijwe neza ether irashonga ako kanya nyuma yo kuvugana namazi kandi ikora ibintu bya gel. Inkoni izenguruka ibikoresho kugirango wirinde molekile y'amazi zikomeje kwinjira. Rimwe na rimwe ntibishobora gutatana kimwe no gushonga ndetse na nyuma yigihe kirekire, gukora igisubizo cya flocculent cyangwa agglomeration. Ibice byiza biratatana kandi bishonga ako kanya nyuma yo kuvugana namazi kugirango akore vicoiner.
PH agaciro ka hydroxypropyl methylcellse ether (kudindiza cyangwa imbaraga zo hambere)
PH agaciro ka hydroxypropyl methylcellsel methycellse ether murugo no mumahanga igenzurwa ahanini nka 7, ari muri leta ya acide. Kuberako haracyari umubare munini wimiterere yimpeta ya anhyglucluse mumiterere ya selile ya selile, impeta ya anhydbucocose niyo tsinda nyamukuru ritera simedion. Impeta ya anhydroglucose irashobora gutuma calcium ions mubisubizo bya symetion itanga isuku yisukari-calcium yamashusho ya CALCROSIDE na Calcium Crystal winjiza na Calcium inzira. Niba agaciro ka PH kari muri leta ya alkaline, minisiteri izagaragara muburyo bwambere. Noneho inzenga nyinshi zikoresha karoti ya sodium kugirango uhindure agaciro PH. Sodium karubone ni ubwoko bwihuse-igenamigambi. Cardonate ya sodium itezimbere imikorere yubuso bwa sima, iteza imbere ubumwe hagati yibice, kandi bikarushaho guteza imbere virtar. Muri icyo gihe, sodiyumu karubone yihutiye guhuza na Calcium ions muri minisiteri kugira ngo iteze imbere ishyirwaho ry'umwanditsi, maze sima yahumuriye vuba. Kubwibyo, agaciro ka PH kagomba guhindurwa ukurikije abakiriya batandukanye mumikorere nyayo.
Umutungo ushinga ikirere wa HydroxyPropyl Methyl Cellulose Ether
Ingaruka zishingiye ku kirere za hydroxyPropyl methylcellsellse ether ni cyane cyane ether na selile nayo ni ubwoko bwabaga. Igikorwa cyo kubangamira selile kibaho cyane cyane kuri gaze-amazi meza. Ubwa mbere, intangiriro yibituba byikirere, hakurikiraho gutandukana no gutegera. Uburenganzira bwa Cellulose burimo amatsinda ya alkyl, bigabanya cyane imbaraga zubuso ningufu zamazi, bigatuma byoroshye kubyara byinshi bifunze mugihe cyo kwizirika ku gisubizo cyamazere.
Gel imitungo ya hydroxypropyl methyl selile
Nyuma ya hydroxypropyl methylcellse ether ishonga muri minisiteri, amatsinda ya hydlexylepyle azakirana na calcium, kugirango uzuze inyenzi zubutaka kandi wuzuze sima. , kunoza ubwumvikane bwa minisiteri, bigira uruhare rwo kuzura no gushimangira. Ariko, iyo matrix ihuriweho ni igitutu, polymer ntishobora kugira uruhare rukomeye ishyigikira, bityo imbaraga no kuzenguruka igihugu cya mirtar.
Gushiraho firime ya hydroxypropyl methyl selile
Nyuma ya HydroxyPropyl Methyl Cellulose Ether yongeyeho kuri hydration, urwego ruto rwa firime ya latex rwakozwe hagati yimpapuro za sima. Iyi filime ifite ingaruka zigurumana kandi itezimbere ubuzima bwa minisiteri. Due to the good water retention of hydroxypropyl methylcellulose ether, enough water molecules are stored inside the mortar, thereby ensuring the hydration hardening of the cement and the full development of the strength, improving the bonding strength of the mortar, and at the same time It improves the cohesion of the mortar, makes the mortar have good plasticity and flexibility, and reduces the shrinkage and deformation of the minisiteri.
