Kukhathamiritsa kwa putty ndi gypsum powder pophatikiza methylhydroxyethylcellulose (MHEC). MHEC ndi polima yopangidwa ndi cellulose yomwe imagwiritsidwa ntchito kwambiri muzomangamanga chifukwa chosunga madzi, makulidwe ake komanso ma rheological properties. Kafukufukuyu adafufuza momwe MHEC imakhudzira magwiridwe antchito a putty ndi stucco, kuphatikiza kugwira ntchito, kumamatira komanso nthawi yoyika. Zomwe zapezazi zimathandizira kuwongolera bwino komanso kupezeka kwa zida zomangira zofunikazi.
dziwitsani:
1.1 Mbiri:
Putty ndi stucco ndizofunikira pomanga, kupereka malo osalala, kuphimba zolakwika, ndi kupititsa patsogolo kukongola kwa nyumbayo. Makhalidwe azinthu izi, monga processability ndi adhesion, ndizofunikira kwambiri kuti zitheke bwino. Methylhydroxyethylcellulose (MHEC) yakopa chidwi chifukwa cha kuthekera kwake kopititsa patsogolo ntchito zomangira.
1.2 Zolinga:
Cholinga chachikulu chinali kuphunzira zotsatira za MHEC pa katundu wa putty ndi gypsum powder. Zolinga zachindunji zimaphatikizanso kuwunika momwe zinthu ziliri, mphamvu ya ma bond, ndi kukhazikitsa nthawi yokwanira kupanga zinthuzi.
kusanthula kwazolemba:
2.1 MHEC mu zomangira:
Kafukufuku wam'mbuyomu adawonetsa kusinthasintha kwa ma MHEC popititsa patsogolo magwiridwe antchito azinthu zosiyanasiyana zomangira, kuphatikiza matope opangidwa ndi simenti ndi zinthu zopangidwa ndi gypsum. Kuwunika kwa mabuku kumafufuza njira zomwe MHEC imakhudza kugwira ntchito, kusunga madzi, ndi kumamatira.
2.2 Maphikidwe a putty ndi pulasitala:
Kumvetsetsa zosakaniza ndi zofunikira za putty ndi gypsum powder ndikofunikira kuti mupange kusakaniza kothandiza. Gawoli likuwunikiranso zolembedwa zakale ndikuzindikira madera omwe angawongolere magwiridwe antchito ndi kukhazikika.
njira:
3.1 Kusankha kwazinthu:
Kusankha mosamala zipangizo, kuphatikizapo putty ndi gypsum powder komanso MHEC, ndizofunikira kuti tikwaniritse zotsatira zomwe mukufuna. Phunziroli likufotokoza ndondomeko ya zipangizo zomwe zimagwiritsidwa ntchito komanso zifukwa zomwe amasankha.
3.2 Mapangidwe oyesera:
Dongosolo loyesera mwadongosolo linapangidwa kuti liwunikenso momwe madera osiyanasiyana a MHEC amayendera pamitengo ya putty ndi stucco. Zofunikira zazikulu monga kugwirira ntchito, kulimba kwa ma bond ndi nthawi yoyika zimayesedwa pogwiritsa ntchito njira zoyeserera zofananira.
Zotsatira ndi zokambirana:
4.1 Kukhazikika:
Mphamvu ya MHEC pakugwira ntchito kwa putty ndi stucco imawunikidwa kudzera m'mayesero monga kuyezetsa kwa benchi ndi kuyesa kwa slump. Zotsatirazo zidawunikidwa kuti zitsimikizire kuchuluka kwabwino kwa MHEC komwe kumawongolera kuwongolera bwino popanda kusokoneza katundu wina.
4.2 Mphamvu yomatira:
Kulimba kwa mgwirizano wa putty ndi stucco ndikofunikira kwambiri momwe amalumikizirana ndi magawo osiyanasiyana. Mayesero otulutsira kunja ndi miyeso ya mphamvu ya mgwirizano anachitidwa kuti ayese zotsatira za MHEC pa kumamatira.
4.3 Khazikitsani nthawi:
Kukhazikitsa nthawi ndi gawo lofunikira lomwe likukhudza kugwiritsa ntchito ndi kuyanika kwa putty ndi stucco. Kafukufukuyu adafufuza momwe magawo osiyanasiyana a MHEC amakhudzira nthawi yokhazikitsa komanso ngati pali njira yoyenera yogwiritsira ntchito.
Pomaliza:
Phunziroli limapereka chidziwitso chofunikira pakukhathamiritsa kwa ma putty ndi gypsum powders pogwiritsa ntchito MHEC. Kupyolera mu kufufuza mwadongosolo zotsatira za MHEC pakugwira ntchito, mphamvu za mgwirizano ndi nthawi yokhazikitsa, phunziroli linapeza njira yabwino yopititsira patsogolo ntchito yonse. Zotsatirazi zitha kuthandizira kupanga zida zomangira zomwe zikuyenda bwino komanso zokhazikika.
Mayendedwe amtsogolo:
Kafukufuku wamtsogolo atha kuwunika kukhazikika kwanthawi yayitali komanso kukhazikika kwanyengo kwa ma putty osinthidwa a MHEC ndi ma stuccoes. Kuonjezera apo, kafukufuku wokhudzana ndi kuthekera kwachuma ndi kuchulukira kwa mapangidwe okonzedwa bwino angathandizenso kagwiritsidwe ntchito ka zinthuzi pamakampani omanga.
