Ibakala le-Cosmetic HEC

ibakala CosmeticI-HEC 

I-Hydroxyethyl cellulose, ekubhekiselwa kuyo njenge-HEC, imbonakalo ye-fibrous emhlophe okanye ekhanyayo etyheli eqinileyo okanye umgubo oqinileyo, ongeyotyhefu kwaye ongenancasa, yeye-non-ionic cellulose ether. I-Hydroxyethyl cellulose iyanyibilika ngokulula emanzini, zombini amanzi abandayo kunye nashushu anokunyibilika, isisombululo esinamanzi asinayo iipropathi zejeli, sinokubambelela kakuhle, ukumelana nobushushu, okunganyibilikiyo kwizinyibilikisi eziqhelekileyo zezinto eziphilayo. Iselulosi yeHydroxyethyl yeyona cellulose ibalulekileyo enyibilikayo emanzini okwesibini kuphela kwicarboxymethyl cellulose kunye nehydroxypropyl methyl cellulose kwimarike yehlabathi.

 

Ibakala le-Cosmetic HEC I-Hydroxyethyl cellulose hydroxyethyl cellulose yi-arhente esebenzayo yokwenza ifilimu, i-adhesive, thickener, stabilizer kunye ne-dispersant kwi-shampoo, izitshizi zeenwele, i-neutraizer, ukunakekelwa kweenwele kunye nezithambiso. Kwipowder yokuhlamba luhlobo lokungcola kwakhona - i-agent yokumisa; I-detergent equkethe i-hydroxyethyl cellulose inesici esicacileyo sokuphucula ukugudisa kunye ne-mercerization yelaphu.

 

Indlela yokulungisa i-HEC ye-Hydroxyethyl cellulose kukubeka i-pulp yomthi, uboya be-cotton kunye ne-sodium hydroxide reaction, ukuze ufumane imveliso ye-alkali cellulose njengento ekrwada, emva kokubetha kwi-kettle yokusabela, phantsi kweemeko ze-vacuum kwi-nitrogen, kwaye udibanise I-epoxy ethane i-reactivity ye-liquid eluhlaza yayiye yongeza i-ethanol, i-acetic acid, i-glyoxal, ukucoca, i-neutralization kunye ne-crosslinking reaction of ageing, Ekugqibeleni, imveliso egqityiweyo ilungiswa ngokuhlamba, ukuchithwa kwamanzi kunye nokomisa.

I-Cosmetic grade HEC I-Hydroxyethyl cellulose ene-thickening, i-bonding, i-emulsion, ukumiswa, ukubunjwa kwefilimu, ukugcinwa kwamanzi, ukulwa nokubola, ukuzinza kunye nezinye iimpawu, inokusetyenziswa ngokubanzi kwi-oyile yokugaya i-agent ye-ejenti yokuqina, i-dispersant, ipeyinti kunye nemveliso ye-inki , isizinzi, iresin, ukuveliswa kweplastiki ye-dispersant, i-ejenti yokulinganisa impahla, izinto zokwakha ezifana nesamente kunye ne-gypsum binder, i-thickener, i-arhente yokugcina amanzi, i-arhente yokuxhoma kunye ne-surfactant kwiimveliso zemichiza yemihla ngemihla, i-arhente yokukhululwa eqhubekayo kwintsimi yamachiza, ifilimu yokugubungela ithebhulethi, i-blocker. kwizixhobo ze-skeleton, i-adhesive kunye ne-stabilizer ye-electronic industry, njl.

Kwimakethi yaseTshayina, ukusetyenziswa kwe-hydroxyethyl cellulose kugxininiswe kakhulu kwizinto zokwaleka, iikhemikhali zemihla ngemihla, i-petroleum kunye namanye amashishini, kwaye ngaphantsi kwezinye iindawo. Ukongezelela, imveliso ye-hydroxyethyl cellulose e-China ikakhulu yimveliso ephantsi, kwaye ukusetyenziswa kwayo kugxininiswe kakhulu kwiingubo eziphantsi kunye neemveliso zemichiza yemihla ngemihla. Kwimarike ephezulu, inani lamashishini afanelekileyo e-China lincinci, imveliso ayinelanga, kwaye ukuxhomekeka kwangaphandle kukhulu. Iqhutywe yi-supply-side reform kunye nemigaqo-nkqubo yokukhusela indalo, i-China ye-hydroxyethyl i-cellulose imboni yesakhiwo ihlala ihlengahlengisa kwaye iphucula, kwaye izinga lendawo yemarike ephezulu iya kuqhubeka nokuphucula kwixesha elizayo.

I-HEC I-Hydroxyethyl cellulose yimveliso ebalulekileyo ye-cellulose ether ebekwe kwindawo yesithathu kwimveliso kunye neentengiso zehlabathi. I-cellulose engenamanzi e-soluble engekho i-ionic, enokuthi isetyenziswe ngokubanzi kwi-petroleum, ipeyinti, inki yokushicilela, i-textile, izinto zokwakha, iikhemikhali zemihla ngemihla, amayeza, i-electronics kunye namanye amashishini, kunye nendawo yokuphuhlisa imarike ebanzi. Iqhutywa yimfuno, imveliso ye-hydroxyethyl cellulose e-China iyenyuka. Ngokuphuculwa kokusetyenziswa kunye nokuqiniswa kwemigaqo-nkqubo yokukhusela indalo, ishishini liphuhlisa ukuya kwinqanaba eliphezulu. Amashishini angakwaziyo ukuhambelana nesantya sophuhliso kwixesha elizayo aya kupheliswa ngokuthe ngcembe.

I-Hydroxyethyl cellulose kwizinto zokuthambisa, iimveliso zokunakekelwa kwesikhumba yeyona ndima iphambili ye-hair conditioner, i-ejenti yokwenza ifilimu, i-emulsifying stabilizer, i-adhesive, i-risk factor yi-1, ikhuselekile ngokufanelekileyo, inokuqinisekiswa ukuba isetyenziswe, kuba abafazi abakhulelweyo abanalo isiphumo, i-hydroxyethyl cellulose. akanawo amaqhakuva .

I-Hydroxyethyl cellulose sisincamathelisi se-polymer eyenziweyo esetyenziswa kwizinto zokuthambisa njenge-conditioner yolusu, i-agent eyenza ifilimu kunye ne-antioxidant.

 

Imiba ekufuneka iqatshelwe xa usebenzisazokuthambisaibakalaI-HECi-hydroxyethyl cellulose:

1. Ngaphambi nangemva kokongezwa kwe-cosmetic grade HEC hydroxyethyl cellulose, ukuvuselela kufuneka kuqhutyekwe kude kube isisombululo sicacile kwaye sicacile.

2. Hluza ibakala lokuthambisa i-HEC i-hydroxyethyl cellulose kwitanki yokuxuba kancinane. Musa ukuyongeza ngobuninzi okanye ngokuthe ngqo kwitanki yokuxuba.

 

3. I-solubility ye-cosmetic grade HEC i-hydroxyethyl cellulose ngokucacileyo ihambelana nobushushu bamanzi kunye nexabiso le-PH, ngoko ke ingqwalasela ekhethekileyo kufuneka ihlawulwe kuyo.

4. Ungaze wongeze into yealkaline kumxube phambi kokuba umgubo we-hydroxyethyl cellulose upholiswe ngamanzi. Ukunyusa ixabiso le-PH emva kokufudumala kunceda ukunyibilika.

5. Ukuba kunokwenzeka, yongeza isithinteli sokungunda kwangoko.

6. Xa usebenzisa i-viscosity ephezulu ye-cosmetic grade HEC hydroxyethyl cellulose, ukuxinwa kotywala komama akufanele kube ngaphezu kwe-2.5-3%, ngaphandle koko utywala oomama kunzima ukusebenza. Iselulosi ye-hydroxyethyl yasemva kokunyangwa ngokuqhelekileyo ayilulanga ukwenza i-clumps okanye i-spheres, kwaye ayiyi kubumba i-colloids engqukuva enganyibilikiyo emva kokongeza amanzi.
