HPMC, kapena Hydroxypropyl Methylcellulose, ndi gawo lofunika kwambiri pakupanga khoma la putty.Pofotokozera mwatsatanetsatane, ndikofunikira kufotokoza mbali zosiyanasiyana, kuphatikiza kapangidwe kake ka mankhwala, gawo la khoma la putty, maubwino, kugwiritsa ntchito, ndi malingaliro ogwiritsidwa ntchito.
1.Mapangidwe a Chemical ndi Katundu:
Hydroxypropyl Methylcellulose (HPMC) ndi ya banja la cellulose ethers.Mapangidwe ake amakhala ndi maunyolo am'mbuyo a cellulose okhala ndi hydroxypropyl ndi magulu a methyl ophatikizidwa.Kapangidwe ka mankhwalawa kamapereka zinthu zosiyanasiyana ku HPMC, kuphatikiza:
Kusunga Madzi: HPMC imatha kusunga madzi, omwe ndi ofunikira kuti asunge kusasinthika koyenera mu zosakaniza za khoma.
Kukhuthala: Imagwira ntchito ngati thickening, zomwe zimathandizira kukhuthala kofunikira kwa putty.
Kugwira ntchito: HPMC imakulitsa kugwirira ntchito popititsa patsogolo kufalikira komanso kuchepetsa kuchepa pakagwiritsidwe ntchito.
Kumanga: Kumathandiza kumangirira zigawo zina za putty pamodzi, zomwe zimapangitsa kumamatira kumagawo.
2.In wall putty formulations, HPMC imagwira ntchito zingapo:
Consistency Control: Imathandizira kusungitsa kofunikira kwa putty nthawi yonse yomwe ikugwiritsiridwa ntchito, kuwonetsetsa kufalikira kosalala komanso kofanana.
Kusunga Madzi: Posunga madzi mkati mwa osakaniza, HPMC imalepheretsa kuyanika msanga, kulola nthawi yokwanira yogwiritsira ntchito ndikuchiritsa.
Kupititsa patsogolo Kumata: HPMC imathandizira kumamatira kwa khoma la putty ku magawo osiyanasiyana monga konkire, pulasitala, ndi malo omanga.
Crack Resistance: Zomwe zimamangiriza zimathandizira ku mphamvu yonse ya putty, kuchepetsa mwayi wa ming'alu yomwe ipangike pakuwumitsa.
3.Ubwino wa HPMC mu Wall Putty:
Kupititsa patsogolo Kugwira Ntchito: HPMC imawonetsetsa kugwiritsa ntchito mosavuta ndikufalikira kwa khoma, ngakhale pamalo oyimirira, kuchepetsa ntchito.
Kukhazikika Kwambiri: Kugwiritsa ntchito HPMC kumapangitsa kukhazikika komanso moyo wautali wa putty wosanjikiza pochepetsa kuchepa ndi kusweka.
Kukaniza Madzi: HPMC imathandizira kukana kulowa kwa madzi, potero imateteza gawo lapansi ku zowonongeka zokhudzana ndi chinyezi.
Kugwirizana: Zimagwirizana ndi zowonjezera zambiri ndi ma pigment omwe amagwiritsidwa ntchito popanga khoma la putty, zomwe zimapangitsa kuti pakhale kusinthasintha pamapangidwe azinthu.
Magwiridwe Osasinthika: HPMC imapereka mawonekedwe osasinthika ku khoma la putty m'malo osiyanasiyana achilengedwe komanso zochitika zogwiritsira ntchito.
4.Wall putty formulations yomwe ili ndi HPMC imapeza ntchito zambiri mu:
Mkati ndi Kunja Kwakhoma: Amagwiritsidwa ntchito kusalaza ndi kusanja pakhoma asanapente kapena kuyika mapepala, kupereka maziko ofanana.
Kukonza ndi Kusamalira: Wall putty yokhala ndi HPMC imagwiritsidwa ntchito kukonza zolakwika zazing'ono zam'mwamba ndi ming'alu, kubwezeretsa kukongola kwa makoma.
Zomaliza Zokongoletsera: Zimakhala ngati maziko opangira zokongoletsera, zomwe zimathandiza kugwiritsa ntchito mitundu yosiyanasiyana ndi zokutira kuti zikhale zokongoletsa.
5.Ngakhale HPMC imapereka maubwino ambiri, kugwiritsa ntchito moyenera kumafuna chidwi pazinthu zina:
Mlingo Woyenera: Mlingo woyenera wa HPMC uyenera kutsimikiziridwa potengera zofunikira za khoma la putty formulation, poganizira zinthu monga kusasinthika komwe kufunidwa komanso momwe mungagwiritsire ntchito.
Kuyesa Kugwirizana: Kugwirizana ndi zosakaniza zina ndi zowonjezera ziyenera kutsimikiziridwa kudzera mu kuyesa kwa labotale kuti zitsimikizire magwiridwe antchito komanso kukhazikika kwa chinthu chomaliza.
Chitsimikizo Chabwino: Ndikofunikira kupeza HPMC yapamwamba kwambiri kuchokera kwa ogulitsa odziwika kuti atsimikizire kusasinthika ndi kudalirika pamapangidwe a khoma.
Kusungirako ndi Kagwiridwe: Malo oyenera osungira, kuphatikizapo kutetezedwa ku chinyezi ndi kutenthedwa kwambiri, ndizofunikira kuti HPMC ikhale yokhulupirika komanso kuti ikhale ndi nthawi yayitali.
Hydroxypropyl Methylcellulose (HPMC) imagwira ntchito yofunika kwambiri pakupanga ma putty putty, ndikupereka maubwino angapo monga kukhazikika kwa magwiridwe antchito, kulimba, komanso kumamatira.Kugwiritsiridwa ntchito kwake mwanzeru, pamodzi ndi kulingalira mozama za zofunikira za kapangidwe ndi mikhalidwe yogwiritsira ntchito, kumathandizira kuti pakhale mapangidwe apamwamba kwambiri a khoma la putty omwe ali oyenera kumanga ndi kukonzanso ntchito zosiyanasiyana.
