Kuyini i-hydroxypropyl methyl cellulose?

I-Hydroxypropyl methyl cellulose (HPMC), eyaziwa nangokuthi i-hydroxypropyl methylcellulose, i-cellulose hydroxypropyl methyl ether, i-cellulose, i-2-hydroxypropylmethyl ether, i-PROPYLENE GLYCOL ETHER OF METHYLCELLULOSE, i-CAS No. 9004-65-3, yenziwe nge-cellulose ecotton emsulwa kakhulu nge-etherification ekhethekile ngaphansi kwezimo ze-alkaline. I-HPMC ingahlukaniswa ngebanga lesakhiwo, ibanga lokudla kanye nebanga lemithi ngokuya ngokusetshenziswa kwayo. Isetshenziswa kabanzi ekwakheni, ekudleni, emithini nasezimonyweni, kumakhemikhali ansuku zonke nakwezinye izimboni.

Yiziphi izindlela zokusebenzisa i-HPMC?

Imboni yokwakha

1. Udaka lokubumba
Ukuqinisa ukunamathela ebusweni bokwakha kungathuthukisa ukugcinwa kwamanzi, ngaleyo ndlela kuthuthukise amandla e-mortar, futhi kuthuthukise ukuthambisa kanye ne-plasticity ukusiza ukusebenza kokwakha. Ukwakhiwa okulula konga isikhathi futhi kuthuthukisa ukusebenza kahle kwezindleko.
2. Imikhiqizo ye-Gypsum
Kungandisa isikhathi sokusebenza kwe-mortar futhi kukhiqize amandla aphezulu okusebenza ngesikhathi sokuqina. Ukwembozwa kobuso obusezingeni eliphezulu kwakhiwa ngokulawula ukuhambisana kwe-mortar.
3. Upende ophuma emanzini kanye nomshini wokususa upende
Ingandisa isikhathi sokuphila kwayo eshalofini ngokuvimbela imvula eqinile, futhi ihambisana kahle kakhulu kanye nokuzinza okuphezulu kwebhayoloji. Izinga layo lokuncibilika liyashesha futhi akulula ukulihlanganisa, okuwusizo ekwenzeni lula inqubo yokuxuba. Ikhiqiza izici ezinhle zokugeleza, kufaka phakathi ukuchitheka okuphansi kanye nokulingana okuhle, iqinisekise ukuqeda okuhle kakhulu kobuso, futhi ivimbele ukugoba kopende. Thuthukisa i-viscosity ye-remover yopende esekelwe emanzini kanye ne-organic solvent pendi remover, ukuze i-remover yopende ingaphumi ebusweni be-workpiece.
4. Ingcina yethayela le-ceramic
Izithako zokuxuba ezomile kulula ukuzixuba futhi azihlangani, okusindisa isikhathi sokusebenza ngoba zisetshenziswa ngokushesha nangendlela ephumelelayo, okuthuthukisa ukucutshungulwa futhi kunciphisa izindleko. Thuthukisa ukusebenza kahle kokufaka amathayili futhi unikeze ukunamathela okuhle kakhulu ngokwandisa isikhathi sokupholisa.
5. Izinto zokwakha phansi ezizilinganisayo
Inikeza ukujiya futhi ingasetshenziswa njengesithako esivimbela ukuminyana ukuze kusizwe ekuthuthukiseni ukusebenza kahle kwephansi. Ukulawula ukugcinwa kwamanzi kunganciphisa kakhulu imifantu nokuncipha.
6. Ukukhiqizwa kwama-slab ekhonkrithi akhiwe
Ithuthukisa ukucutshungulwa kwemikhiqizo ekhishwe, inamandla aphezulu okubopha kanye nokuthamba, futhi ithuthukisa amandla amanzi kanye nokunamathela kwamashidi akhishwe.
7. Isigcwalisi sepuleti
I-Hydroxypropyl methyl cellulose inokugcinwa kwamanzi okuhle kakhulu, ingandisa isikhathi sokupholisa, futhi ukuthambisa kwayo okuphezulu kwenza ukusetshenziswa kube bushelelezi kakhudlwana. Ithuthukisa ngempumelelo ikhwalithi yomphezulu, inikeze ukuthungwa okubushelelezi nokulinganayo, futhi yenza umphezulu wokubopha uqine kakhudlwana.
8. I-gypsum esekelwe kusimende
Inokugcinwa kwamanzi amaningi, yandisa isikhathi sokusebenza kwe-mortar, futhi ingalawula nokungena komoya, ngaleyo ndlela isuse imifantu emincane yengubo futhi yakhe indawo ebushelelezi.

Imboni yokudla

1. Ama-citrus asemathinini: ukuvimbela ukuba mhlophe nokuwohloka ngenxa yokubola kwama-glycosides e-citrus ngesikhathi sokugcina, ukuze kufezwe umphumela wokugcina okusha.
2. Imikhiqizo yezithelo ezibandayo: engezwa kujusi wezithelo kanye neqhwa ukuze kwenziwe ukunambitheka kube ngcono.
3. Isosi: isetshenziswa njengesiqinisi se-emulsion noma isiqinisi sesosi kanye ne-tomato paste.
4. Ukumbozwa nokupholishwa ngamanzi abandayo: okusetshenziselwa ukugcina izinhlanzi eziqandisiwe ukuvimbela ukushintsha kombala kanye nokuwohloka kwekhwalithi. Ngemva kokumbozwa nokupholishwa nge-methyl cellulose noma isixazululo samanzi se-hydroxypropyl methyl cellulose, qandisa ungqimba lweqhwa.
5. I-Adhesive yamathebulethi: Njenge-adhesive yokubumba yamathebulethi nama-granule, "inokuwa okuhle ngesikhathi esisodwa" (ukuncibilika okusheshayo, ukuwa kanye nokuhlakazeka lapho ithathwa).

Imboni yezemithi

1. Ukumboza: I-ejenti yokumboza yenziwe ibe yisisombululo se-organic solvent noma isixazululo samanzi sokuphathwa kwethebhulethi, ikakhulukazi ukumboza izinhlayiya ezilungisiwe ngesifutho.
2. I-ejenti ebambezelayo: amagremu angu-2-3 ngosuku, 1-2G ngesikhathi, izinsuku ezingu-4-5.
3. Umuthi wamehlo: Njengoba ingcindezi ye-osmotic yesisombululo samanzi se-methyl cellulose ifana neyezinyembezi, ayicasuli kakhulu amehlo. Ifakwa kumuthi wamehlo njengesithambisi sokuxhumana nelensi yamehlo.
4. Ijeli: Isetshenziswa njengesisekelo sejeli njengomuthi wangaphandle noma amafutha.
5. I-ejenti yokufutha: isetshenziswa njengesithambisi kanye ne-ejenti yokugcina amanzi.

Imboni yezimonyo

1. I-shampoo: Thuthukisa ukujiya kanye nokuqina kwama-bubble e-shampoo, i-washing agent kanye ne-detergent.
2. I-Toothpaste: kuthuthukisa ukugeleza kwe-toothpaste.

Imboni ye-Kiln

1. Izinto ze-elekthronikhi: njenge-adhesive yokwakha umshini we-ceramic electric compactor kanye ne-ferrite bauxite magnet, ingasetshenziswa kanye ne-1.2-propanediol.
2. Umuthi we-Glaze: osetshenziswa njengomuthi we-glaze we-ceramics futhi uhlanganiswe nopende we-enamel, ongathuthukisa ukubopha kanye nokucutshungulwa.
3. Udaka oluyi-refractory: Lungafakwa kudaka oluyi-refractory noma ezintweni zesithando esibunjiwe ukuze kuthuthukiswe ukuqina nokugcinwa kwamanzi.

Eminye imikhakha

I-HPMC isetshenziswa kabanzi nakwi-resin yokwenziwa, i-petrochemical, izinto zobumba, ukwenza amaphepha, isikhumba, uyinki osekelwe emanzini, ugwayi kanye neminye imboni. Isetshenziswa njengesithambisi, isihlakazi, isihlanganisi, i-emulsifier kanye nesiqinisi embonini yezindwangu.

Ungayibona kanjani ikhwalithi ye-hydroxypropyl methyl cellulose (HPMC) ngokubona?

1. I-Chromaticity: yize ingakwazi ukuhlonza ngqo ukuthi i-HPMC kulula ukuyisebenzisa, futhi uma i-ejenti yokwenza mhlophe ingezwa ekukhiqizweni, ikhwalithi yayo izothinteka. Kodwa-ke, imikhiqizo esezingeni eliphezulu isizothengwa.
2. Ubunono: I-HPMC inama-meshe angu-80 nama-meshe angu-100 ngokujwayelekile, kanti ama-meshe angu-120 angaphansi. Ama-HPMC amaningi anama-meshe angu-80. Ngokuvamile, ubunono be-offside bungcono.
3. Ukudlulisa ukukhanya: faka i-hydroxypropyl methyl cellulose (I-HPMC) emanzini ukuze kwakheke i-colloid esobala, bese ubona ukuhanjiswa kwayo kokukhanya. Uma ukuhanjiswa kokukhanya kukhulu, kungcono, okubonisa ukuthi kukhona into encane engancibiliki kuyo.
4. Amandla adonsela phansi athile: Uma amandla adonsela phansi athile esinda kakhulu, kuba ngcono. Isilinganiso sibalulekile, ngokuvamile ngoba okuqukethwe yi-hydroxypropyl kuphezulu. Uma okuqukethwe yi-hydroxypropyl kuphezulu, ukugcinwa kwamanzi kungcono.
I-Hydroxypropyl methyl cellulose izinzile kuma-acid nama-base, futhi isixazululo sayo samanzi sizinzile kakhulu ku-pH=2~12. Singumkhiqizi ochwepheshe. Uma udinga lo mkhiqizo, ungaxhumana nathi. Konke lokho kungenxa yokwabelana nge-HPMC kule nkinga. Ngithemba ukuthi ingakusiza uqonde i-HPMC.
