Hydroksipropil metil celuloza (HPMC)<\/strong><\/a> je vodotopni eter z odli\u010dnimi zmogljivostmi, ki je narejen iz naravnega polimernega materiala celuloze in obdelan z vrsto kemikalij. HPMC se lahko uporablja v gradbenih materialih, industriji prevlek, keramiki, medicini, prehrani, tekstilu, kmetijstvu, vsakodnevnih kemi\u010dnih izdelkih in drugih industrijah.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Z dodatkom HPMC se delovna obstojnost gradbenih materialov znatno izbolj\u0161a. Na primer, malta brez dodatka HPMC je bolj ohlapna in la\u017eje izgublja vodo, medtem ko je z dodatkom HPMC povr\u0161ina malte gladka in trdno pritrjena na podlago, kar podalj\u0161uje \u010das uporabe in je primerno za velike stavbe.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Cementni ali gipsni izdelki se podvr\u017eejo hidratacijski reakciji z vodo, zato ti izdelki lahko dose\u017eejo dolo\u010deno trdnost. \u010ce ni vode, reakcija se ne bo zgodila in trdnosti ne bo. Visokokakovostni HPMC se enakomerno in u\u010dinkovito razporedi v cementni malti in gipsnih izdelkih, zatesni vse trdne delce in tvori vla\u017eilni film. Voda v matriki se postopoma spro\u0161\u010da skozi \u010das in tvori hidrat z anorganskim cementnim materialom, kar povzro\u010di zadr\u017eevanje vode. Najpomembnej\u0161a vloga HPMC je pove\u010danje zadr\u017eevanja vode v gradbenih materialih in izbolj\u0161anje njihove lepilne trdnosti. <\/strong>)<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Z dodajanjem HPMC se se lepilne sposobnosti cementnega malta in izdelkov na osnovi gipsa znatno izbolj\u0161ajo, kar lahko zagotovi, da se plo\u0161\u010dice ne bodo zdrsnile in da bosta gips in podlaga trdno povezani. Vendar pa koli\u010dina dodanega HPMC ne sme biti prevelika, saj bo material po eni strani lepljiv in bo prilepil na gradbene orodje, kar bo povzro\u010dalo nev\u0161e\u010dnosti pri gradnji, po drugi strani pa se bo material pojavil z votlimi prazninami. \u010ce ne morete zagotoviti ustrezne koli\u010dine HPMC, ki jo je treba dodati, ali viskoznosti HPMC, se lahko posvetujete z na\u0161imi strokovnjaki, kontaktirali vas bomo \u010dim prej.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
