1 He aha nā hoʻohana nui o ka cellulose ether HPMC?
Hoʻohana nui ʻia ʻo HPMC i ka mortar kūkulu hale, ka pena wai, ka resin synthetic, nā keramika, nā lāʻau lapaʻau, ka meaʻai, ka lole, nā mea hoʻonani, ka paka, a me nā ʻoihana ʻē aʻe. Ua māhele ʻia i ke ʻano kūkulu hale, ka ʻano meaʻai, ka ʻano lāʻau lapaʻau, ka ʻano ʻoihana PVC a me ke ʻano kemika o kēlā me kēia lā.
2 He aha nā hoʻokaʻawale ʻana o ka cellulose?
ʻO nā cellulose maʻamau ʻo MC, HPMC, MHEC, CMC, HEC, EC
I waena o lākou, hoʻohana nui ʻia ʻo HEC a me CMC i nā uhi wai;
Hiki ke hoʻohana ʻia ʻo CMC i nā pālolo, nā kahua aila, ka meaʻai a me nā mahina ʻai ʻē aʻe;
Hoʻohana nui ʻia ʻo EC i ka lāʻau lapaʻau, ka hoʻopili kālā uila a me nā mahina ʻē aʻe;
Ua māhele ʻia ʻo HPMC i nā kikoʻī like ʻole a ua hoʻohana ʻia i loko o ka wili, lāʻau lapaʻau, meaʻai, ʻoihana PVC, nā huahana kemika o kēlā me kēia lā a me nā ʻoihana ʻē aʻe.
3He aha ka ʻokoʻa ma waena o HPMC a me MHEC ma ke noi?
Ua like like nā ʻano o nā ʻano cellulose ʻelua, akā ʻoi aku ka maikaʻi o ke kūpaʻa wela kiʻekiʻe o MHEC, ʻoi aku hoʻi i ke kauwela ke kiʻekiʻe ka mahana o ka paia, a ʻoi aku ka maikaʻi o ka hana paʻa wai o MHEC ma mua o ko HPMC ma lalo o nā kūlana wela kiʻekiʻe.
4 Pehea e hoʻoholo maʻalahi ai i ka maikaʻi o HPMC?
1) ʻOiai ʻaʻole hiki i ka keʻokeʻo ke hoʻoholo inā maʻalahi ka hoʻohana ʻana o HPMC, a inā hoʻohui ʻia nā mea keʻokeʻo i ke kaʻina hana, e hoʻopilikia ʻia ka maikaʻi, akā ʻo ka hapa nui o nā huahana maikaʻi he keʻokeʻo maikaʻi, hiki ke hoʻoholo ʻia mai ke ʻano.
2) Ka hoʻoili ʻana o ka mālamalama: Ma hope o ka hoʻoheheʻe ʻana o ka HPMC i loko o ka wai e hana i kahi colloid moakaka, e nānā i kona hoʻoili ʻana o ka mālamalama. ʻOi aku ka maikaʻi o ka hoʻoili ʻana o ka mālamalama, ʻoi aku ka liʻiliʻi o ka mea hiki ʻole ke hoʻoheheʻe ʻia, a maikaʻi ke ʻano.
Inā makemake ʻoe e hoʻoholo pololei i ka maikaʻi o ka cellulose, ʻo ke ʻano hilinaʻi loa ka hoʻohana ʻana i nā lako ʻoihana i loko o kahi keʻena hoʻokolohua ʻoihana no ka hoʻāʻo ʻana. ʻO nā ʻōkuhi hoʻāʻo nui e pili ana i ka viscosity, ka nui o ka paʻa ʻana o ka wai, a me ka nui o ka lehu.
5 Ke ʻano ʻike viscosity o ka cellulose?
ʻO NDJ ka viscometer maʻamau i ka mākeke cellulose kūloko, akā ma ka mākeke honua, hoʻohana pinepine nā mea hana like ʻole i nā ʻano hoʻāʻo viscosity like ʻole. ʻO nā mea maʻamau ʻo Brookfeild RV, Hoppler, a aia kekahi mau hopena ʻike like ʻole, i māhele ʻia i ka hopena 1% a me ka hopena 2%. ʻO nā viscometers like ʻole a me nā ʻano ʻike like ʻole e hopena pinepine i kahi ʻokoʻa o nā manawa he nui a i ʻole nā ʻumi manawa i nā hopena viscosity.
6He aha ka ʻokoʻa ma waena o ke ʻano koke HPMC a me ke ʻano hoʻoheheʻe wela?
ʻO nā huahana koke a HPMC e pili ana i nā huahana e hoʻopuehu koke ana i ka wai anuanu, akā pono e hoʻomaopopo ʻia ʻaʻole ia he manaʻo o ka hoʻopuehu ʻana. Hoʻohana ʻia nā huahana koke me ka glyoxal ma luna o ka ʻili a hoʻopuehu ʻia i ka wai anuanu, akā ʻaʻole lākou e hoʻomaka koke e hoʻoheheʻe. , no laila ʻaʻole i hana koke ʻia ka mānoanoa ma hope o ka hoʻopuehu ʻana. ʻO ka nui o ka mālama ʻana i ka ʻili glyoxal, ʻo ka wikiwiki o ka hoʻopuehu ʻana, akā ʻo ka lohi o ka mānoanoa, ʻo ka liʻiliʻi o ka nui o ka glyoxal, a ʻo ka hope.
7 hui pū ʻia ka cellulose a me ka cellulose i hoʻololi ʻia
I kēia manawa, he nui nā cellulose i hoʻololi ʻia a me ka cellulose hui ʻia ma ka mākeke, no laila he aha ka hoʻololi ʻana a me ka hui ʻana?
Loaʻa pinepine i kēia ʻano cellulose nā waiwai i loaʻa ʻole i ka cellulose mua a i ʻole hoʻomaikaʻi i kekahi o kona mau waiwai, e like me: anti-slip, hoʻonui i ka manawa wehe, hoʻonui ʻia ka wahi scraping e hoʻomaikaʻi i ke kūkulu ʻana, a pēlā aku. Eia nō naʻe, pono e hoʻomaopopo ʻia he nui nā ʻoihana e hoʻohana pū ana i ka cellulose makepono āna e hoʻopili ai i mea e hōʻemi ai i nā kumukūʻai ua kapa ʻia ʻo compound cellulose a i ʻole modified cellulose. Ma ke ʻano he mea kūʻai aku, e hoʻāʻo e hoʻokaʻawale a mai hoʻopunipuni ʻia. ʻOi aku ka maikaʻi o ke koho ʻana i nā huahana hilinaʻi mai nā lama nui a me nā hale hana nui.
