Ikiganiro ku ngaruka zo kongeramo Hydroxypropyl Methyl Cellulose kumiterere ya Mortar

Hydroxypropyl methylcellulose HPMC irashobora kunoza cyane gufata amazi ya minisiteri. Igipimo cyo hasi cya hydroxypropyl methylcellulose HPMC irashobora kuzamura cyane igipimo cyo gufata amazi ya minisiteri. Iyo igipimo ari 0,02%, igipimo cyo gufata amazi cyiyongera kuva kuri 83% cyazamutse kigera kuri 88%; iyo dosiye yari 0.2%, igipimo cyo gufata amazi cyageze kuri 97%. Muri icyo gihe, ibirimo bike bya HPMC bigabanya kandi cyane urugero rwo gusiba no kuva amaraso ya minisiteri, ibyo bikaba byerekana ko HPMC idashobora gusa kunoza imikoreshereze y’amazi ya minisiteri, ahubwo inatezimbere cyane ubumwe bwa minisiteri. ni ngombwa kuburinganire bwubwubatsi bwa minisiteri. ni byiza cyane.

Nyamara, hydroxypropyl methylcellulose HPMC ifite urwego runaka rwingaruka mbi kumbaraga zingirakamaro nimbaraga zo kwikuramo za minisiteri. Hamwe no kwiyongera kwa hydroxypropyl methylcellulose HPMC, imbaraga zihindagurika nimbaraga zo kwikuramo za minisiteri byagabanutse buhoro buhoro. Muri icyo gihe, hydroxypropyl methylcellulose HPMC irashobora kongera imbaraga zingana za minisiteri. Iyo ibikubiye muri hydroxypropyl methylcellulose HPMC iri muri 0.1%, imbaraga zingana za minisiteri ziyongera ubudahwema hamwe no kwiyongera kwa HPMC, mugihe iyo ibirimo birenze 0.1%, imbaraga za tensile ntizongera kwiyongera cyane. Hydroxypropyl methylcellulose HPMC irashobora kandi kongera cyane imbaraga zo gukata imitsi ya minisiteri. Ongeraho 0.2% HPMC irashobora gutuma imbaraga zububiko bwa minisiteri ziva kuri 0,72MPa ziyongera kuri 1.16MPa.

Ubushakashatsi bwerekanye ko hydroxypropyl methylcellulose HPMC ishobora kongera igihe kinini cyo gukonjesha cya minisiteri kandi ikagabanya cyane kunyerera kwa minisiteri, ifasha cyane mukubaka paste. Iyo HPMC itongeyeho, imbaraga zububiko bwa minisiteri yakonje muminota 20 igabanuka kuva 0.72MPa ikagera kuri 0.54MPa. Nyuma yo kongeramo 0.05% na 0.1% HPMC, imbaraga zububiko bwa minisiteri yakonje muminota 20 ni 0.8MPa na 0.84MPa. Iyo HPMC itongeyeho, kunyerera ya minisiteri ni 5.5mm. Hamwe no kwiyongera kwa HPMC, kunyerera bigabanuka ubudahwema. Iyo ibirimo ari 0.2%, kunyerera kwa minisiteri bigabanuka kugera kuri 2,1mm, kandi kunyerera biragabanuka cyane. Nubundi buryo bworoshye bwubaka butanga inkunga ya tekiniki.

Byongeye kandi, hydroxypropyl methylcellulose HPMC irashobora kubuza neza gukora ibice bya plastike muri minisiteri kandi bikagabanya cyane ibice bya plastiki. Iyo ibiri muri HPMC ari bike, indangagaciro yo kugabanuka igabanuka cyane hamwe no kwiyongera kwibirimo bya HPMC. Iyo ibikubiye muri HPMC ari 0.1% na 0.2%, igipimo cyerekana ibipimo bya minisiteri ni 63% na 50%. Nyuma yibiri muri HPMC birenze 0.2%, Ibice bya plastike bya minisiteri ntibikigabanuka cyane.
