Mu myaka yashize, imyenda ishingiye ku mazi yamenyekanye cyane kubera kurengera ibidukikije, uburozi buke, no kubaka byoroshye.Kugirango uzamure imikorere nibiranga iyi myenda, inyongeramusaruro zitandukanye zirakoreshwa, kimwe mubyongeweho ni hydroxypropyl methylcellulose (HPMC).Iyi selile ya selile ifite uruhare runini mugutezimbere ubwiza, ituze, gufatana hamwe nubwiza rusange bwamazi ashingiye kumazi.
Wige ibya HPMC
Hydroxypropylmethylcellulose, ikunze kwitwa HPMC, ni polymer itandukanye ikomoka kuri selile, ibintu bisanzwe biboneka murukuta rw'utugingo ngengabuzima.Binyuze mu ruhererekane rw'imiti ihindura, selile ihindurwa muri HPMC, ikora polymer-amazi-elegitoronike hamwe na porogaramu nyinshi.HPMC irangwa no guhuza kwihariye kwa hydrophobi methyl na hydrophilic hydroxypropyl matsinda, bikayemerera guhindura imiterere ya rheologiya ya sisitemu y'amazi.
Imikorere ya HPMC mumazi ashingiye kumazi
Kugenzura ubukonje:
HPMC irazwi cyane kubushobozi ifite bwo kugenzura ububobere bwamazi ashingiye kumazi.Muguhindura intumbero ya HPMC, abayikora barashobora kugera kubwububiko bwifuzwa cyangwa ubunini, bikavamo gukoresha neza no gukwirakwiza.
Guhagarara no guhagarara neza:
Kwiyongera kwa HPMC byongera ituze ryamazi ashingiye kumazi kandi bikarinda kugabanuka cyangwa gutonyanga mugihe cyo kubaka.Ibi ni ingenzi cyane cyane hejuru yubutumburuke aho kugumana igifuniko bitoroshye.
Kunoza gukomera:
HPMC ifasha kunoza igifuniko kijyanye na substrate zitandukanye kugirango zirambe, ziramba.Ibi ni ingenzi cyane kumarangi yo hanze ahura nikirere gitandukanye.
Kubika amazi:
HPMC izwiho kuba ifite amazi agumana amazi, akaba afite akamaro mukurinda gukama irangi imburagihe mugihe cyo kuyisaba.Ibi byemeza kurangiza ndetse no kurangiza.
Thixotropy:
Imiterere ya thixotropique ya HPMC ituma irangi rishobora gukoreshwa byoroshye nimbaraga nke mugihe gikomeza guhoraho mugihe kitari mukigenda.Iyi mikorere ifite agaciro cyane mukugabanya spatter mugihe cyo gusaba.
Gukoresha HPMC mumazi ashingiye kumazi
Imyenda y'imbere n'inyuma:
HPMC ikoreshwa cyane mumazi yo hanze no hanze ashingiye kumazi kugirango atezimbere imikorere yabo muri rusange.Ifasha kugera ku buryo bunoze, ndetse no kurangiza mugihe utanga kurinda ibidukikije.
Irangi ry'imyenda:
Imyenda yimyenda, ikoreshwa muburyo bwo gushushanya, yungukirwa no kugenzura imvugo itangwa na HPMC.Ifasha kugumana imiterere yifuzwa no kugaragara.
Primer and Sealer:
Muri primers na kashe, aho gufatira hamwe no gukwirakwiza substrate ari ngombwa, HPMC ifasha kunoza imiterere no gushiraho firime, bikavamo imikorere myiza muri rusange.
Masonry na stucco impuzu:
HPMC irashobora gukoreshwa mububiko bwa masonry na stucco, bigatanga ubukonje bukenewe hamwe na anti-sag bisabwa nibi bikoresho byihariye.
Ibiti:
Ibiti biva mu mazi byungukira ku bushobozi bwa HPMC bwo kongera imbaraga no kwirinda kugabanuka, bigatuma iherezo rirambye kandi riramba ku biti.
Inyungu zo gukoresha HPMC mumazi ashingiye kumazi
Ibidukikije byangiza ibidukikije:
HPMC ikomoka ku mutungo ushobora kuvugururwa kandi igira uruhare mu bidukikije byangiza ibidukikije bishingiye ku mazi.Ibinyabuzima byangiza ibinyabuzima byongera imbaraga zo gutwikira.
Kunoza imashini:
Igenzura rya rheologiya ritangwa na HPMC ryorohereza amazi ashingiye kumazi byoroshye gukoresha, haba kuri brush, roller cyangwa spray, biteza imbere gukwirakwiza no kubishyira mubikorwa.
Kongera igihe kirekire:
HPMC itezimbere kandi ihamye, ifasha kongera igihe kirekire no kuramba kurangi rishingiye kumazi, bikagabanya gukenera gusiga kenshi.
Guhindura:
HPMC ni inyongeramusaruro inyuranye ishobora gukoreshwa muburyo butandukanye bushingiye kumazi ashingiye kumazi kugirango habeho insimburangingo zitandukanye nuburyo bwo gukoresha.
Igiciro kinini:
HPMC ikora neza kandi igahindura ibintu bifasha kugabanya ingano ya pigment nizindi nyongeramusaruro zihenze zisabwa muburyo bwo gutwikira, bikavamo kuzigama amafaranga.
mu gusoza
Hydroxypropylmethylcellulose (HPMC) ninyongera yingirakamaro yibikorwa byinshi mumazi ashingiye kumazi.Imiterere yihariye, harimo kugenzura ibicucu, kongera umutekano, kunoza imitekerereze hamwe n’ibidukikije byangiza ibidukikije, bituma iba ikintu cyingirakamaro kubakora ibicuruzwa bitwikiriye intego yo gukora ibicuruzwa byiza kandi byangiza ibidukikije.Mugihe icyifuzo cyibicuruzwa birambye kandi byorohereza abakoresha bikomeje kwiyongera hamwe nisoko ryambarwa, HPMC ikomeje kugira uruhare runini mugushinga ibishishwa byamazi byujuje imikorere nibidukikije.
