Ingakanani izinga lokusetyenziswa kwe-HPMC?

I-Hydroxypropyl methylcellulose (HPMC)yi-ether ebalulekileyo ye-nonionic cellulose ether esetyenziswa kakhulu kumashishini ahlukeneyo, kuquka ulwakhiwo, amayeza, ukutya, kunye nezinto zokuthambisa. Abantu abaninzi bakhathazekile malunga nesantya sokusetyenziswa kwe-HPMC. Nangona kunjalo, idosi ayimiselwanga; iyahluka ngokuxhomekeke kushishino, uhlobo lwemveliso, iimfuno zokusebenza, kunye nokwakheka kwayo.

1. Izinga lokusetyenziswa kwe-HPMC kwiShishini loKwakha

Ishishini lokwakha lelinye lawona misebenzi iphambili ye-HPMC, ngakumbi kwi-dry-mix mortar, i-tile adhesive, i-putty powder, i-self-leveling mortar, kunye ne-thermal insulation mortar. I-HPMC isebenza kakhulu ukugcina amanzi, ukutyeba, kunye nokuphucula ukusebenza kakuhle. Izinga lokusetyenziswa kwayo lidla ngokuba phakathi kwe-0.2% ukuya kwi-0.8%, ngolu hlobo lulandelayo:

I-adhesive yethayile: Umlinganiselo we-HPMC ngokubanzi uphakathi kwe-0.3% kunye ne-0.5%, uhlengahlengiswa ngokusekelwe kwisantya sokufunxwa kwamanzi kwethayile, indawo yokwakha, kunye nomgangatho we-adhesive.

I-wall putty: Umlinganiselo oqhelekileyo yi-0.2% ukuya kwi-0.4% ukuqinisekisa ukuba umphezulu we-putty uthambile, ongenaziqhekeko. I-self-leveling mortar: Umlinganiselo oqhelekileyo yi-0.1% ukuya kwi-0.3%, kwaye kufuneka ulawulo lwe-viscosity ukuze kugcinwe ukunyibilika.

Ukufakwa kwesamente: Umthamo we-HPMC ngokubanzi yi-0.3% ukuya kwi-0.6% ukuphucula ukugcinwa kwamanzi kunye nokunamathela, kunye nokuthintela ukuqhekeka nokuqhekeka.

Izinto ezichaphazela idosi ziquka i-viscosity grade ye-HPMC (ii-grade eziqhelekileyo ziquka i-40,000 mPa·s, i-75,000 mPa·s, kunye ne-100,000 mPa·s), ukwenziwa kwemveliso, ubushushu bokusetyenziswa, kunye neempawu zesamente.

2. Ukusetyenziswa kwe-HPMC kwiShishini leMithi

Kwicandelo lezonyango, i-HPMC ayisetyenziswa rhoqo njengezinto zokugquma iipilisi, iifomyula ezikhutshwa rhoqo, kunye neegobolondo zekhaphu, kodwa ifuna ubunyulu obuphezulu kakhulu kunye nokhuseleko. Ukusetyenziswa Okuqhelekileyo:

Ukwambathisa iipilisi: Ngokubanzi i-2% ukuya kwi-5% yobunzima beepilisi isetyenziselwa ukulawula izinga lokunyibilika nokuphucula inkangeleko.

Iipilisi ezikhutshwa rhoqo: Umxholo we-HPMC ungafikelela kwi-10% ukuya kwi-40%, usebenza njengesixhobo sokulibazisa ukukhutshwa kwamayeza. Iipilisi ezingenanto: I-HPMC phantse sisithako esiphambili kwiipilisi, ingaphezulu kwe-50%.

3. Ukusetyenziswa kwe-HPMC kwiShishini lokuTya

I-HPMC isetyenziswa njengesithambisi-mafutha, isinyibilikisi-mafutha, kunye nesiqinisi ekutyeni, kwaye isetyenziswa kakhulu kwiimpahla ezibhakiweyo, iziselo, kunye neemveliso zobisi ezinamafutha aphantsi. Amanqanaba okusetyenziswa aqhele ukuba phakathi kwe-0.1% ukuya kwi-0.5%. Umzekelo:

I-ayisikhrim: I-ayisikhrim eyongeziweyo malunga ne-0.2% ukuphucula incasa nokuthintela ukwakheka kwekristale yeqhwa.

Izinto ezibhakiweyo: Zongezwa malunga ne-0.3% ukuze kugcinwe umswakama kwaye kuthambe.

4. Ukusetyenziswa kwe-HPMC kwiShishini leeKhemikhali zemihla ngemihla

I-HPMC isetyenziswa njengesithambisi kunye nesithambisi kwi-shampoos, ii-shawa gels, kunye neemveliso zokhathalelo lolusu, ngesiqhelo kumlinganiselo wokusetyenziswa we-0.3% ukuya kwi-1.0%. Phakathi kwezi:

I-shampoo: 0.3% ukuya kwi-0.6% yongezwa ukuphucula iimpawu ze-rheological kunye nokuziva.

Iiloshini zokunyamekela ulusu: Malunga ne-0.5% ukuya kwi-1.0% zongezwa ukuphucula ukusasazeka nokwakha ifilimu yokufumisa.

5. Izinto eziphambili ezichaphazela izinga lokusetyenziswa kwe-HPMC

Uhlobo lweMveliso: Iinkqubo ezahlukeneyo zinemfuno ezahlukeneyo, umz., i-mortar > ukutya.

Ukuxinana kwe-HPMC: Ukuxinana okuphezulu kwe-HPMC ifuna idosi ephantsi, kodwa igcina amanzi kakuhle.

Ubushushu kunye neNdalo: Ukusetyenziswa kobushushu obuphezulu kufuna ukugcinwa kwamanzi okuphezulu, nto leyo enyusa ukusetyenziswa kwe-HPMC.

Ukuhlanganiswa kweFormulation: Ukusetyenziswa kweHPMC kungancitshiswa ukuba iRDP okanye i-starch ether isetyenziswa njenge-assistant.

Akukho mgangatho umiselweyo wokusetyenziswa kwe-HPMC; kufuneka ilungelelaniswe neemfuno ezithile zoshishino kunye nokwakheka. Ngokubanzi, izinga lokusetyenziswa kwishishini lokwakha yi-0.2%-0.6%, kwishishini lamayeza linokuba phezulu ukuya kwi-40%, kwishishini lokutya limalunga ne-0.1%-0.5%, kwaye kwiimveliso zeekhemikhali zemihla ngemihla yi-0.3%-1.0%.Ukukhetha uhlobo olufanelekileyo lwe-HPMCkwaye idosi ayiphuculi nje kuphela ukusebenza kwemveliso kodwa ikwalawula neendleko ngempumelelo.
