HPMC yogwiritsidwa ntchito mu Wall Putty/Skim Coat

2024-01-02

HPMC, kapena Hydroxypropyl Methyl Cellulose, imagwira ntchito zosiyanasiyana kutengera mtundu wake. Ku China, imagwiritsidwa ntchito kwambiri popanga zinthu. Makamaka, popanga ma wall putty kapena skim coat, ufa wambiri wa skim coat, kuphatikizapo HPMC ndi zinthu zina za ufa, umasakanizidwa bwino kenako n’kusungunuka powonjezera madzi. Njira imeneyi imaletsa kusonkhana chifukwa cha kusungunuka kwa tinthu ta HPMC m’madzi nthawi yomweyo.


Kutentha kwa gel ya HPMC kumadalira kuchuluka kwa methoxy yake; kuchuluka kochepa kwa methoxy kumabweretsa kutentha kwakukulu kwa gel. HPMC yosungunuka nthawi yomweyo m'madzi ozizira, yothiridwa ndi glyoxal, imafalikira mwachangu m'madzi ozizira, zomwe zimapangitsa kuti kukhuthala kuchuluke koma osati kusungunuka kwathunthu. Kumbali inayi, HPMC yosungunuka nthawi zonse, yopanda chithandizo cha glyoxal, imafalikira mwachangu koma imakhala ndi kukhuthala pang'onopang'ono ndi kuchuluka kochepa. HPMC ikhoza kugawidwa m'magulu awiri: mitundu ya nthawi yomweyo ndi mitundu yosungunuka nthawi yomweyo. Zinthu zomwe zimasungunuka nthawi yomweyo zimafalikira mwachangu m'madzi ozizira ndipo pang'onopang'ono zimawonjezera kukhuthala, ndikupanga colloid yowoneka bwino. Mitundu yosungunuka nthawi yomweyo, yoyenera kudulidwa ndi matope, imawonetsa kusakanikirana kwa guluu wamadzimadzi ndi zokutira.


Kupanga kwa HPMC kumaphatikizapo njira yosungunulira pogwiritsa ntchito toluene kapena isopropyl alcohol. Kugwiritsa ntchito ufa wa skim coat kumafuna kukhuthala kochepa, pafupifupi 10,000, makamaka kuteteza madzi. Kugwiritsa ntchito matope kumafuna kukhuthala kwakukulu, pafupifupi 15,000, pomwe kugwiritsa ntchito guluu kumafuna zinthu zomwe nthawi yomweyo zimakhala ndi kukhuthala kwakukulu. Kuchuluka kwenikweni kwa HPMC komwe kumagwiritsidwa ntchito kumasiyana malinga ndi nyengo, kutentha kwa chilengedwe, mtundu wa calcium wa imvi wakomweko, njira yochepetsera kukhuthala, ndi zofunikira za makasitomala.


HPMC, yokhala ndi kukhuthala kwa ufa wa skim coat wa 100,000, imagwira ntchito yofunika kwambiri pakusunga ndi kukhuthala kwa madzi. Komabe, pakugwiritsa ntchito moyenera, kukhuthala kwa 70,000 mpaka 80,000 ndikovomerezeka. Ntchito yayikulu ya HPMC mu skim coat imaphatikizapo kukhuthala, kusunga madzi, ndikuthandizira kumanga. Sichita nawo machitidwe a mankhwala koma imathandizira kupewa mapangidwe a thovu poonetsetsa kuti liuma bwino.


Ubale pakati pa ufa wa putty/skimcoat ndi mtundu wa calcium wa phulusa ndi wofunika kwambiri, pomwe mphamvu ya HPMC ndi yochepa. Udindo wa HPMC pakusunga madzi ungakhudze kugwa kwa ufa, ndipo kuyanjana kwake ndi madzi panthawi yogwiritsa ntchito skimcoat kumakhudza momwe mankhwala amachitira, ndikupanga chinthu chatsopano (calcium carbonate). Komabe, HPMC yokha sichita nawo izi.


Mafomula osiyanasiyana a ufa wa putty wa pakhoma amakwaniritsa zosowa zosiyanasiyana, monga putty wamba wa pakhoma, putty wa pakhoma wolimba kwambiri, putty wa pakhoma wosalowa madzi, putty wa pakhoma wolimba kwambiri, putty wa pakhoma wotha kutsukidwa ndi kuuma, ndi putty wa pakhoma wotha kutsukidwa wotha kusweka, pakati pa ena. Fomula iliyonse imafotokoza kuchuluka kwa ufa wa Redispersible Polymer Powder (RDP), ufa wa double fly, ufa wa calcium wa imvi, simenti yoyera, ndi HPMC, zomwe zimagwiritsidwa ntchito pazinthu zina monga matope, guluu, kapena zokutira.
