Hiki ke hoʻokaʻawale ʻia ka HPMC i nā ʻano hikiwawe a me ka wela.Ke hoʻopuehu wikiwiki a emi ka wai anuanu i loko o ka wai, hiki ke hoʻokaʻawale ʻia ka HPMC i nā ʻano hikiwawe a me ka wela.I kēia manawa, ʻaʻohe viscosity ka wai, no ka mea, ua hoʻopuehu wale ʻia ka HPMC i ka wai, ʻaʻohe manaʻo maoli o ka heheʻe.Ma hope o 2min, hoʻonui mālie ka viscosity o ka wai, e hana ana i kahi hopena colloid viscous.Ke hōʻiliʻili ʻia nā mea hoʻoheheʻe organik wela i loko o ka wai anuanu, hiki iā lākou ke hoʻopuehu wikiwiki i ka wai wela a hoʻopau i ka wai wela.Ke hoʻemi ʻia ka mahana ambient i kekahi degere o ka wela, e hele mālie ka viscosity a hiki i ka hoʻopuka ʻana o kahi hopena colloidal viscous piha.Hoʻohana wale ʻia ke ʻano o ka mea hoʻoheheʻe kūlohelohe i ka pauka putty a me ka mortar.I loko o ka superglue wai a me nā uhi, aia ka heluna kanaka ʻaʻole hiki ke hoʻohana ʻia.Loaʻa i ka ʻano hikiwawe - solubility ka māhele noi maʻamau.Hiki ke hoʻohana ʻia e like me ka pauka putty pā o loko a me ka mortar, a me kāna superglue wai a me ka uhi.ʻAʻohe kapu.

ʻO ka heheʻe wai wela: no ka mea ʻaʻole heheʻe ʻo HPMC i ka wai wela, no laila hiki ke hoʻoheheʻe ʻia ʻo HPMC i ka loulou kumu i ka wai wela, a laila hoʻoheheʻe wikiwiki i ka wā hoʻomaha.Ua wehewehe ʻia nā ʻano maʻamau ʻelua penei:

1) E hoʻokomo i ka wai wela e pono ai ʻoe i loko o kahi ipu a wela iā ia ma kahi o 70 ℃.E hoʻohui mālie, e hoʻohui mālie i ka hydroxypropyl methyl cellulose, e lana mālie ka HPMC ma ka muliwai, a laila e hoʻohua mālie i ka sludge refrigeration sludge i ka hui ʻana.

2) E hoʻohui i ka 1/3 a i ʻole 2/3 o ka wai i loko o ka moku, e wela i ka 70 ℃, e hoʻomehana iā 70 ℃ e hoʻopuehu i ka HPMC, a e hoʻomākaukau i ka lepo wai wela;Hoʻohui ʻia ke koena wai anuanu i ka ʻōpala wela a hui pū ʻia me ka hui ʻana ma hope o ka hoʻoluʻu.

ʻO ke ʻano o ka hui ʻana o ka pauda: ʻO ka pauka HPMC me ka mea huila a me nā mea ʻē aʻe he nui nā mea kemika pauda i hoʻohui ʻia, a laila hoʻohui i ka wai e hoʻoheheʻe.I kēia manawa, hiki ke hoʻoheheʻe ʻia ka HPMC i ka hihia o ka ʻaʻohe agglomeration, no ka mea, ʻo kēlā me kēia kihi liʻiliʻi he liʻiliʻi wale nō ka pauka HPMC, i ka wā e hoʻoheheʻe koke ai ka wai - ʻo kēia ʻano ala wale nō ka hoʻohana ʻana o ka pā i loko putty pauda a me nā mea hana mortar.[HPMC] ma ke ʻano he mea hoʻomaʻemaʻe a me ka mea hoʻomaʻemaʻe i loko o ka mortar putty o ka paia i loko.

He waimaka waimaka hydroxypropyl methyl cellulose (HMPC) maʻamau kēia, kahi kokoke i ka waiwai viscoelastic (ka nui o ka mucin) i ka waimaka.Hoʻopili ia i ka ʻili o ka maka ma o ka adsorption o ka polymer, a hoʻohālikelike i ka hana o ka conjunctival mucin, i mea e hoʻomaikaʻi ai i ka mokuʻāina o ka mucin i ka maka a hoʻonui i ka hopena pulu o ka cornea.

I ka pauka putty, ka mānoanoa, ka mālama ʻana i ka wai a me ke kūkulu ʻana i ʻekolu mau hana.ʻO ka mānoanoa, cellulose hiki ke mānoanoa a hiki i ka hoʻokuʻu ʻia ʻana, no laila e mau ka hoʻonā ʻana i luna a i lalo i ke ʻano o ke kau ʻana i ka anti-flow.Ka paʻa wai: e hoʻomaloʻo mālie i ka pauka putty, kōkua ka calcium hina i ka hana o ka wai.Hana: cellulose lubrication, hiki ke hana i ka pauka putty maikaʻi ke kūkulu ʻana.ʻAʻole komo ʻo HPMC i nā hopena kemika, akā he kuleana kākoʻo wale nō.

ʻOi aku ka maʻalahi o ka pena kikokikona i ke koho ʻana i ke kala, a hiki ke hoʻokō i ka hopena hoʻolālā kiʻi maikaʻi loa, a ʻo ka pena pōhaku maoli i ka ʻimi ʻana i ke ola maoli, ʻoi aku ka maikaʻi ma mua o ka pena kala, ʻo kēlā me kēia me kona ikaika ponoʻī.ʻO ka pena kikokikona a me ka lacquer i ke kaʻina hana, i mea e mālama mau ai i ka waihoʻoluʻu kumu, maʻamau i ka hana hope loa, pono mākou e hoʻohana i ka varnish (ʻaila māmā) e pīpī e pale i kā lākou hopena kiʻi a i ʻole ka hopena pōhaku.

ʻO Lacquer, ka pena kikokikona he ʻano pena, hoʻohana nui ʻia no ka hoʻonaninani ʻana i ka paia.Ua hōʻuluʻulu ka ʻaoʻao pūnaewele puni honua diatom mud i kekahi mau ʻokoʻa ma waena o ka pena kikokiko a me ka lacquer.

High quality latex kiʻekiʻe kumu kūʻai, nā mea hana i mea e hoola koina, e hoʻohui i ka liʻiliʻi o ka hapa o ka emulsion, ma hope o ka hana ʻana i ka pōhaku pena kiʻi maloʻo maloʻo ʻole, ʻaʻole lawa ka nui, ʻoi aku ka nui o ka bibulous kiʻi pena, ua hoʻemi ʻia ka ikaika compressive, I ka manawa e hālāwai ai me ka ua ua no ka manawa lōʻihi, e komo ka ua i loko o ke kiʻi pena, pena pōhaku maoli ke keʻokeʻo.

ʻO kekahi mau mea hana i ka hana ʻana i ka lacquer, hoʻohui pinepine i ka nui o ka carboxymethyl cellulose, hydroxyethyl cellulose e like me kahi mānoanoa, ʻo kēia mau mea he wai-soluble a hydrophilic, uhi kiʻiʻoniʻoni i waiho ʻia i ka papa, e hoʻemi nui i ka pale wai o ka uhi.
