Zomatira za matailosi zimagwiritsidwa ntchito kwambiri kuyika matailosi pamalo osiyanasiyana monga makoma ndi pansi.Ndikofunikira kuti pakhale mgwirizano wamphamvu pakati pa matailosi ndi gawo lapansi kuti zisawonongeke, ndikuwonetsetsa kuti kuyikako kumatha kupirira zovuta zosiyanasiyana zachilengedwe monga chinyezi, kusintha kwa kutentha ndi kuyeretsa nthawi zonse.
Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito pomatira matayala ndi hydroxypropylmethylcellulose (HPMC), polima yomwe nthawi zambiri imachokera ku cellulose.Amadziwika kuti amatha kusunga madzi, zomwe zimapangitsa kuti zikhale zofunikira kwambiri pakupanga zomatira za matailosi.
Pali zabwino zingapo zogwiritsira ntchito HPMC pamapangidwe omatira matailosi.Izi zikuphatikizapo;
1. Kuwongolera magwiridwe antchito
HPMC imagwira ntchito ngati rheology modifier mu mapangidwe a simenti monga zomatira matailosi, zomwe zikutanthauza kuti zitha kupititsa patsogolo kugwirira ntchito kwa zomatira matailosi.Zimachepetsanso maonekedwe a zotupa ndi ziphuphu, zomwe zimathandizira kusakanikirana kwa kusakaniza, zomwe zimapangitsa kuti oyika azitha kugwira ntchito mosavuta.
2. Kusunga madzi
Chimodzi mwazabwino za HPMC mu zomatira matailosi ndi mphamvu yake yabwino yosungira madzi.Zimatsimikizira kuti zomatirazo zimakhalabe zogwiritsidwa ntchito kwa nthawi yayitali komanso zimathandiza kuti zomatira za matailosi zikhazikike.Mbali imeneyi imachepetsanso chiopsezo cha ming'alu ya shrinkage, yomwe nthawi zambiri imayamba chifukwa cha kutaya madzi panthawi yokhazikitsa.
3. Kuwonjezeka kwa mphamvu
Phindu lina la kugwiritsa ntchito HPMC mu zomatira matailosi ndikuti zimathandiza kuwonjezera mphamvu ya kusakaniza.Kuphatikizika kwa HPMC kumathandizira kukhazikika kosakanikirana, kuwonjezera mphamvu ndikuwongolera kukhazikika kwa zomatira matailosi.
4. Sungani nthawi
Zomata za matailosi zomwe zili ndi HPMC zimafuna kusakanikirana kwapang'onopang'ono ndi nthawi yogwiritsira ntchito chifukwa cha rheology yabwino.Kuphatikiza apo, nthawi yayitali yogwira ntchito yoperekedwa ndi HPMC imatanthawuza kuti madera akuluakulu akhoza kuphimbidwa, zomwe zimapangitsa kuti kuyika matayala mwachangu.
5. Kuchepetsa kuwononga chilengedwe
HPMC ndi chinthu chachilengedwe komanso chosawonongeka.Chifukwa chake, kugwiritsa ntchito HPMC pazomatira matailosi kumatha kuchepetsa kukhudzidwa kwa zomatira ndikukwaniritsa kufunikira kwazinthu zomangira zomwe sizigwirizana ndi chilengedwe.
Mwachidule, HPMC ndi gawo lofunikira popanga zomatira zamatayilo apamwamba kwambiri.Mphamvu yake yosungira madzi ndi kusintha kwa rheological kumapereka zopindulitsa kuphatikizapo kusinthika, kuwonjezereka kwa mphamvu, kuchepa kwa chilengedwe komanso kusunga nthawi.Chifukwa chake, ena opanga zomatira matayala agwiritsa ntchito HPMC kuti apititse patsogolo mphamvu zomangira matayala ndikuwonjezera kulimba kwa zomatira zawo.
