He aha nā hopena i loaʻa iā Cellulose, Starch Ether a me Redispersible Polymer Powder i ka Gypsum Mortar?

Hydroxypropyl Methyl Cellulose HPMC
1. Loaʻa iā ia ka paʻa no ka waikawa a me ka alkali, a paʻa loa kona ʻano wai i ka pH = 2 ~ 12 ākea. ʻAʻole nui ka hopena o ka soda a me ka wai lime i kāna hana, akā hiki i ka alkali ke wikiwiki i kona kahe ʻana a hoʻomaikaʻi iki i ka viscosity.
2. HPMChe mea hoʻopaʻa wai kūpono nopuna malooʻōnaehana, hiki ke hoʻemi i ka helu o ka mortar secretion a me ka stratification, hoʻomaikaʻi i ka cohesiveness o ka mortar, hoʻopau pono i ka hoʻokumu ʻana o nā māwae plastik, a hoʻemi i ka mortar plastic cracking index.
3, he non-ionic a me ka non-polymeric electrolyte, i paʻa loa i nā wai wai o nā paʻakai metala a me nā electrolytes organik, a hiki ke hoʻohui ʻia i nā mea kūkulu hale no ka manawa lōʻihi e hōʻoia i ka hoʻomaikaʻi ʻana o kona mau lōʻihi.
4, ua hoʻomaikaʻi maikaʻi ʻia ka hana hana o ka mortar, ʻo ka mortar me he "ʻaila", hiki ke hana i ka hui piha o ka pā, maʻemaʻe ka ʻili, i paʻa ka mortar a me ka paʻa kumu, a hiki ke hoʻolōʻihi i ka manawa hana.

Paʻa wai
ʻO ka hoʻokō ʻana i ka mālama ʻana i loko e kūpono i ka hoʻomaikaʻi ʻana i ka ikaika lōʻihi, ka pale ʻana i ke koko, ka pale ʻana i ka hoʻoponopono ʻana i ka mortar, ka emi ʻana a me ka hoʻomaikaʻi ʻana i ke kūʻē ʻana o ka mortar.

mānoanoa
Kāohi i ka hoʻokaʻawale ʻana, hoʻomaikaʻi i ka like ʻole o ka mortar, hoʻomaikaʻi i ka ikaika paʻa pulu, a hoʻomaikaʻi i ka hana anti-hanging.

ʻO ka ea entraining
Hoʻomaikaʻi i ka hana mortar. Me ke kiʻekiʻe o ka viscosity o cellulose, ʻoi aku ka lōʻihi o ke kaulahao mole, ʻoi aku ka maopopo o ka hopena entraining ea.

Hoʻopaneʻe ka coagulation
E hui pū me ka hoʻopaʻa ʻana i ka wai e hoʻolōʻihi i ka manawa wehe o ka mortar

Hydroxypropyl Starch etera
1. ʻO ka maʻiʻo hydroxypropyl kiʻekiʻe i loko o ka starch ether e hāʻawi i ka hydrophilicity paʻa paʻa, e hoʻohuli i ka wai manuahi i ka wai paʻa, kahi mea e paʻa ai ka wai maikaʻi.
2. Loa'a nā mana like 'ole o nā ether starch me nā mea hydroxypropyl like 'ole e kōkua i ka cellulose i ka ho'opa'a 'ana i ka wai ma ke ana like.
3. ʻO ka hoʻololi ʻana o ka pūʻulu hydroxypropyl e hoʻonui i ka degere pehu i loko o ka wai a hoʻopaʻa i ka wahi no ka kahe ʻana o ka particle, no laila e loaʻa ai ka hopena o ka mānoanoa a me ka hoʻonui ʻana i ka viscosity.

Thixotropic lubricity
Hoʻopuehu koke ʻia ka starch ether i loko o ka ʻōnaehana mortar, hoʻololi i ka rheology o ka mortar a hāʻawi iā thixotropy. Ke hoʻohana ʻia ka ikaika o waho, e hoʻemi ʻia ka viscosity o ka mortar, e hōʻoia ana i ka hana maikaʻi a me ka pumpability, a hāʻawi iā ia thixotropy. He manaʻo paheʻe kona. Ke hoʻihoʻi ʻia ka ikaika o waho, hoʻonui ka viscosity, e hāʻawi i ka mortar maikaʻi ke kūʻē i ka sagging. Ma waena o nā pauka putty, loaʻa iā ia nā mea maikaʻi o ka hoʻomaikaʻi ʻana i ka ʻōlinolino o ka ʻaila putty a me ka nani o ka poli.

Ka hopena paʻa wai kōkua
Loaʻa iā Starch ether nā waiwai hydrophilic ma muli o ke kuleana o nā hui hydroxypropyl i ka ʻōnaehana. Ke hui pū ʻia me ka cellulose a i ʻole i hoʻohui ʻia i kahi nui i ka mortar, hiki ke hoʻonui i ka paʻa ʻana o ka wai i kekahi ʻano a hoʻomaikaʻi i ka manawa maloʻo o ka ʻili.

Anti-sag a anti-slip
ʻO ka hopena anti-sag maikaʻi loa a me ka hopena hoʻohālike.

ʻO ka pauka polymer hiki ke hoʻokuʻu ʻia
1. E hoʻomaikaʻi i ka hana o ka mortar.ʻO ka pauka hiki ke weher or RDPhoʻopuehu ʻia nā ʻāpana i loko o ka ʻōnaehana, hāʻawi i ka ʻōnaehana i ka wai maikaʻi a hoʻomaikaʻi i ka hana a me ka hana o ka mortar.
2. E hoʻomaikaʻi i ka ikaika hoʻopaʻa ʻana o ka mortar. Ma hope o ka hoʻopuehu ʻia ʻana o ka pauka lāʻau i loko o kahi kiʻiʻoniʻoni, hiki ke hoʻohui pū ʻia nā mea inorganic a me nā mea kūlohelohe i loko o ka ʻōnaehana mortar. Hiki ke noʻonoʻo ʻia ʻo ka sima a me ke one i loko o ka mortar nā iwi, a ʻo ka pauka latex e hana i nā ligaments. Piʻi ka hui ʻana, piʻi ka ikaika, a hoʻokumu ʻia kahi ʻano maʻalahi.
3. E hoʻomaikaʻi i ka pale ʻana i ka wā o ka mortar. ʻO ka pauka latex kūʻokoʻa freeze-thaw he resin thermoplastic me ka maʻalahi maikaʻi, hiki ke hiki i ka mortar ke pane i nā loli o waho i ke anuanu a me ka wela, me ka pale pono ʻana i ka mortar mai ka haki ʻana ma muli o nā loli wela.
4. E hoʻomaikaʻi i ka ikaika flexural o ka mortar. Hoʻohui ka polymer a me ka slurry sima. Ke hana ʻia nā māwae e nā mana o waho, hiki i ka polymer ke span i nā māwae a keʻakeʻa i ka hoʻonui ʻana o nā māwae, a laila e hoʻomaikaʻi ai i ka paʻakikī a me ka deformability o ka mortar.
