Ka hoʻohana ʻana o ka hydroxypropyl methylcellulose i loko o ka pauka putty

He ʻano mea hoʻonaninani hale ka Putty. ʻO ka papa o ka putty keʻokeʻo ma luna o ka ʻili o ka lumi hakahaka i kūʻai ʻia aku nei he ʻoi aku ma mua o 90 i ke keʻokeʻo a ʻoi aku ma mua o 330 i ka maikaʻi. Ua māhele ʻia ka Putty i ka paia o loko a me ka paia o waho. Pono ka putty paia o waho e kū i ka makani a me ka lā, no laila he kiʻekiʻe ke kāpili, ikaika kiʻekiʻe a haʻahaʻa iki ka helu kuhikuhi palekana kaiapuni. ʻO ka helu kuhikuhi piha o ka putty paia o loko he maikaʻi, olakino a palekana kaiapuni, no laila ʻaʻole hoʻohana ʻia ka paia o loko ma waho a ʻaʻole hoʻohana ʻia ka paia o waho i loko. ʻO ka maʻamau, he gypsum a i ʻole ka sima ka putty, no laila he ʻinoʻino ka ʻili a maʻalahi hoʻi e hoʻopaʻa paʻa. Eia nō naʻe, i ka wā o ke kūkulu ʻana, pono nō e hoʻopili i kahi papa o ka mea hoʻopili ma ke kahua kumu e sila i ka papa kumu, a hoʻomaikaʻi i ka hoʻopili ʻana o ka paia, i hiki ai ke hoʻopaʻa maikaʻi ʻia ka putty i ka ʻili kumu.

ʻO ka nui o ka HPMC i hoʻohana maoli ʻia e pili ana i ke kaiapuni o ke aniau, ka ʻokoʻa o ka mahana, ka maikaʻi o ka pauka lehu kalipuna kūloko, ke ʻano huna o ka pauka putty a me "ke ʻano i koi ʻia e ka mea hana". Ma ke ʻano laulā, ma waena o 4kg a me 5kg.

Loaʻa iā 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 hui, akā loaʻa wale ka hopena o ke kōkua. ʻO ka pauka Putty kahi ʻano hopena hui ma ka ʻili wai a ma ka paia,

Kekahi mau pilikia:

1. Wehe ʻana i ka pauka o ka putty

A: Pili kēia i ka nui o ka lime calcium, a pili pū kekahi i ka nui a me ke ʻano o ka cellulose, kahi i hōʻike ʻia ma ka helu paʻa wai o ka huahana. Haʻahaʻa ka helu paʻa wai a ʻaʻole lawa ka manawa hydration o ka lime calcium.

2. Ka ʻili ʻana a me ka ʻōwili ʻana o ka pauka putty

A: Pili kēia i ka nui o ka paʻa ʻana o ka wai. Haʻahaʻa ka mānoanoa o ka cellulose, kahi mea maʻalahi ke hana a liʻiliʻi paha ka nui.

3. Ke kiko o ka nila o ka pauka putty

Pili kēia i ka cellulose, nona ka waiwai hana ʻili maikaʻi ʻole. I ka manawa like, loaʻa i nā mea haumia i loko o ka cellulose kahi hopena iki me ka lehu calcium. Inā ikaika ka hopena, e hōʻike ka pauka putty i ke kūlana o ke koena tofu. ʻAʻole hiki ke hele i ka paia a ʻaʻohe ona ikaika hoʻopaʻa. Eia kekahi, loaʻa pū ia i nā huahana e like me nā hui carboxy i hui pū ʻia me ka cellulose.
