Kwa zaka zambiri, zomangamanga ndi maphewo maphepu akhala zikugwiritsidwa ntchito popanga zokongola komanso zolimba. Ma liva awa amapangidwa kuchokera kusakaniza sing'anga, mchenga, madzi ndi zina zowonjezera. Hydroxypypyl methylcellulose (hpmc) ndiowonjezera.
HPMC, yomwe imadziwikanso kuti hypromellose, ndi ma celluule osinthidwa kuchokera ku mitengo yamitengo ndi ulusi wa thonje. Ndikosafunikira kwa zinthu zosiyanasiyana zomwe amagwiritsa ntchito mafakitale osiyanasiyana, kuphatikizapo kapangidwe kake, mankhwala opangira mankhwala, zakudya ndi zinthu zosamalira pandekha. Mu gawo lomanga, HPMC imagwiritsidwa ntchito ngati thicker, binder, madzi osunga madzi ndi rheology okhazikika pakufalikira.
Udindo wa HPMC mu Masonry Kupanga matope
1. Controtetency Control
Kusasinthika kwa matope ndikofunikira pakugwiritsa ntchito moyenera komanso kugwirizanika. HPMC imagwiritsidwa ntchito kukhalabe osagwirizana ndi zomangamanga ndi maphepo. Imagwira ntchito yopanda tanthauzo, kuletsa matope kuti asakhale madzi ambiri kapena kukulira, kulola kuti pagwiritsidwe ntchito.
2. Kusunga kwamadzi
Madzi ndi ofunikira muyezo wa simenti, gawo lofunikira la zomangamanga ndi matope ozungulira. Komabe, madzi ambiri amatha kuyambitsa shrinkage komanso kusokonekera. HPMC imathandizira kusunga chinyontho mu matope, kulola hydration yoyenera kwa simenti pomwe mukuchepetsa kuchepa kwa madzi kudzera mu eapoph. Izi zimapangitsa kuti pakhale bwino kwambiri, zotsatsa bwino komanso mphamvu zowonjezereka.
3. Nthawi
Nthawi ya matope imakhudza kulimba ndikutsatira mawonekedwe omaliza. HPMC itha kugwiritsidwa ntchito kuwongolera nthawi ya zomangamanga ndi matope. Imagwira ntchito yopumira, ndikuchepetsa mphamvu hydration simenti. Izi zimapangitsa nthawi yogwira ntchito nthawi yayitali komanso kugwira ntchito bwino.
4. Mphamvu ya Adelion
Mphamvu zolimba za matope ndizofunikira kwambiri kukhazikika kwa zomangamanga ndi zida zomangira. HPMC imathandizira kulimba mtima pakati pa matope ndi gawo lapansi popereka zomatira bwino ndikuwongolera kugwiritsidwa ntchito. Izi zimapangitsa kuti mukhale olimba komanso olimba.
Ubwino wa HPMC mu zomanga ndi matope
1. Kupititsa patsogolo kugwirira ntchito
HPMC imathandizira kukonza kugwiritsidwa ntchito kwa zomangamanga ndi matope ozungulira. Kukula kwamphamvu ndi madzi osungika kwa hpmc kupanga matope osavuta komanso osavuta. Izi zimachulukitsa bwino kwambiri komanso kuthamanga kwa zomangamanga.
2. Chepetsani shrinkage ndi kusweka
Shrinkage ndi kusokonezeka ndi mavuto wamba ndi mawonekedwe a miyambo ndi maphepo. Katundu wosunga madzi wa HPMC amachepetsa kusintha ndikupewa shrinkage ndi kusweka. Izi zimapangitsa kukhala kokhazikika komanso kokhazikika.
3. Kulimbikitsa Kulimbikitsidwa
Kuphatikiza kwa hpmc ku maso ndi matope kumapangitsa kulimba kwa maziko omaliza. HPMC yasintha mphamvu yaubwenzi, kusachita bwino komanso kusungidwa kwamadzi, chifukwa champhamvu kwambiri.
4. Ntchito yayikulu
HPMC ndi zowonjezera zotsika mtengo zomwe zimapereka zabwino zambiri m'maso ndi kupaka matope matope. Katundu wake amachepetsa chiopsezo cha mavuto monga shrinkage ndi kusokonekera, potengera ndalama zokonza zonsezo.
Pomaliza
HPMC imagwira ntchito yofunika kwambiri kukonza magwiridwe antchito ndi magwiridwe antchito am'manja ndi matope. Kuwongolera Kwake, kusungidwa kwamadzi, kukhazikitsa nthawi yolamulira ndi mphamvu zogwirizana ndi mphamvu zambiri zopindulitsa pamakampani omanga. Kugwiritsa ntchito kwa HPMC kumapangitsa kuti pakhale bwino kugwirira ntchito, kuchepa komanso kuwonongeka, kukhazikika kwamphamvu komanso zolimbitsa thupi. Kuphatikizika kwa hpmc ku maso kwa matope ndipo mabongo ndi gawo labwino kwambiri lothandiza kwambiri, lokhazikika komanso lokhalokha.
