Hoʻohana i ka hydroxypropyl methylcellulose i ka pauka putty

ʻO Putty kahi ʻano mea hoʻonani hale. ʻO kahi papa putty keʻokeʻo ma ka ʻili o ka lumi hakahaka i kūʻai ʻia ma mua o 90 i ka keʻokeʻo a ʻoi aku ma mua o 330 i ka nani. Hoʻokaʻawale ʻia ʻo Putty i ka paia o loko a me ka paia o waho. Pono ka putty pā waho e kūʻē i ka makani a me ka lā, no laila he kiʻekiʻe ke kāpili, ikaika kiʻekiʻe a haʻahaʻa haʻahaʻa haʻahaʻa. ʻO ka papa kuhikuhi piha o ka putty wall interior he maikaʻi, olakino a me ka palekana o ke kaiapuni, no laila ʻaʻole hoʻohana ʻia ka pā o loko ma waho a ʻaʻole hoʻohana ʻia ka pā o waho i loko. ʻO ka maʻamau, ʻo ka putty ka gypsum a i ʻole ka cement-based, no laila ʻoʻoleʻa ka ʻili a maʻalahi ke hoʻopaʻa paʻa. Eia nō naʻe, i ka wā o ke kūkulu ʻana, pono nō e hoʻopili i kahi papa o ka mea hoʻopili ma ka papa kumu e sila ai i ka papa kumu, a hoʻomaikaʻi i ka pili ʻana o ka pā, i hiki ke hoʻopaʻa maikaʻi ʻia ka putty i ka ʻili kumu.

ʻO ka nui o ka HPMC i hoʻohana maoli ʻia ma muli o ke ʻano o ke aniau, ka ʻokoʻa o ka mahana, ka maikaʻi o ka pauka lehu calcium kūloko, ka mea huna huna o ka pauka putty a me "ka maikaʻi i koi ʻia e ka mea hana". ʻO ka maʻamau, ma waena o 4kg a me 5kg.

Loaʻa i ka HPMC ka hana o ka lubrication, hiki ke hana i ka pauka putty i ka hana maikaʻi. ʻAʻole komo ʻo Hydroxypropyl methylcellulose i kekahi hopena hoʻohuihui, akā loaʻa wale ka hopena o ke kōkua. ʻO ka pauka Putty kahi ʻano hoʻohuihui ma ka ʻili wai a ma ka paia,

ʻO kekahi mau pilikia:

1. Wehe ka pauda o ka putty

A: E pili ana kēia i ke ʻano o ka lime calcium, a pili pū kekahi i ke ʻano a me ka maikaʻi o ka cellulose, i hōʻike ʻia i ka pae paʻa wai o ka huahana. He haʻahaʻa ka paʻa wai a ʻaʻole lawa ka manawa hydration o ka lime calcium.

2. ʻO ka ʻili a me ka ʻōwili ʻana i ka pauka putty

A: Pili kēia i ka nui o ka mālama ʻana i ka wai. He haʻahaʻa ka viscosity cellulose, hiki ke maʻalahi a liʻiliʻi paha ka dosage.

3. ʻO ke kiko nila o ka pauka putty

Pili kēia i ka cellulose, nona ka waiwai hana kiʻiʻoniʻoni maikaʻi ʻole. I ka manawa like, loaʻa i nā haumia i loko o ka cellulose kahi hopena liʻiliʻi me ka calcium lehu. Inā ikaika ka hopena, e hōʻike ka pauda putty i ke ʻano o ke koena tofu. ʻAʻole hiki ke hele i ka pā a ʻaʻohe ikaika hoʻopaʻa. Eia kekahi, loaʻa ia i nā huahana e like me nā hui carboxy i hui pū ʻia me ka cellulose.
