Hydroxyethylcellulose (HEC) yog ib qho dej-soluble polymer compound uas tau siv dav hauv cov khoom tu tus kheej xws li da dej gel thiab xab npum ua kua. Nws lub luag haujlwm tseem ceeb yog ua cov thickener, stabilizer thiab emulsifier los txhim kho lub cev thiab cov neeg siv kev paub ntawm cov khoom.
(1). Kev siv HEC hauv da dej gel
Da dej gel yog ib yam khoom siv tu tus kheej uas nws lub luag haujlwm tseem ceeb yog ntxuav daim tawv nqaij. HEC ua lub luag haujlwm tseem ceeb hauv cov gel da dej, thiab nws cov ntawv thov tshwj xeeb yog raws li hauv qab no:
1.1 Thickening nyhuv
HEC tuaj yeem ua kom cov viscosity ntawm da dej gel, muab nws zoo sib xws thiab fluidity. Qhov no tsis tsuas yog pab txhim kho kev ntxhib los mos ntawm cov khoom, tab sis kuj tiv thaiv cov khoom los ntawm stratifying los yog nyob rau hauv lub raj mis. Los ntawm kev tswj hwm tus nqi ntawm HEC ntxiv, viscosity ntawm da dej gel tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm cov neeg siv khoom sib txawv.
1.2 Stabilizing nyhuv
Raws li ib tug stabilizer, HEC tuaj yeem tiv thaiv cov khoom xyaw nquag hauv cov gel da dej los ntawm kev sib cais lossis kev daws teeb meem. Nws tuaj yeem tsim ib qho kev sib xyaw ntawm cov dej theem thiab cov roj theem, kom ntseeg tau tias cov khoom tseem ruaj khov thaum khaws cia thiab siv. Lub xub ntiag ntawm HEC yog qhov tseem ceeb tshwj xeeb hauv cov gels da dej uas muaj cov roj yam tseem ceeb lossis lwm cov khoom xyaw tsis zoo.
1.3 Moisturizing nyhuv
HEC muaj cov khoom zoo moisturizing thiab tuaj yeem tsim cov yeeb yaj kiab moisturizing ntawm daim tawv nqaij kom tsis txhob poob dej. Qhov no yuav pab kom cov tawv nqaij moisturized thiab ua rau cov neeg siv xis thiab moisturized tom qab siv cov gel da dej. Thaum siv ua ke nrog lwm cov moisturizers, HEC tuaj yeem txhim kho cov nyhuv moisturizing ntawm cov khoom.
(2). Kev siv HEC hauv kua xab npum
Cov xab npum ua kua yog lwm yam khoom siv tu tus kheej, feem ntau yog siv los ntxuav tes thiab lub cev. Daim ntawv thov ntawm HEC hauv cov kua xab npum zoo ib yam li cov gel da dej, tab sis nws kuj muaj nws tus kheej cov yam ntxwv:
2.1 Txhim kho ua npuas ncauj zoo nkauj
HEC tuaj yeem txhim kho cov npuas dej ntawm cov kua xab npum, ua rau nws muag muag thiab kav ntev. Txawm hais tias HEC nws tus kheej tsis yog tus neeg sawv cev foaming, nws tuaj yeem pab tswj kev ruaj ntseg ntawm cov npuas dej los ntawm kev ua kom cov viscosity thiab stability ntawm cov kua. Qhov no ua rau cov kua xab npum nplua nuj nyob hauv ua npuas ncauj thiab yooj yim rau yaug thaum siv.
2.2 Tswj fluidity
Cov kua xab npum feem ntau yog ntim rau hauv lub raj mis, thiab fluidity yog ib qho ntawm nws cov yam ntxwv tseem ceeb. Cov nyhuv thickening ntawm HEC tuaj yeem pab kho qhov fluidity ntawm cov kua xab npum, ua rau nws tsis nyias los yog tuab heev thaum tso tawm, ua kom yooj yim rau cov neeg siv. Fluidity tsim nyog kuj tseem tuaj yeem zam cov khoom pov tseg ntau dhau thiab xyuas kom meej tias qhov ntau npaum li cas siv txhua zaus yog nruab nrab.
2.3 Muab kev nkag siab ntawm lubrication
Thaum lub sij hawm ntxuav tes, HEC tuaj yeem muab qee qhov kev nkag siab ntawm lubrication thiab txo cov tawv nqaij sib txhuam. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov neeg siv uas nquag siv cov xab npum ua kua, vim nws tuaj yeem txo qhov kev pheej hmoo ntawm cov tawv nqaij qhuav thiab ntxhib. Tshwj xeeb tshaj yog nyob rau hauv cov kua xab npum uas muaj cov tshuaj tua kab mob, cov nyhuv lubricating ntawm HEC tuaj yeem txo cov tawv nqaij tsis xis nyob los ntawm cov khoom xyaw detergent ntau dhau.
(3). Kev ceev faj rau kev siv
Txawm hais tias HEC muaj ntau qhov zoo hauv cov khoom siv tu tus kheej, kuj tseem muaj qee yam uas yuav tsum nco ntsoov thaum siv nws:
3.1 Ntxiv nyiaj tswj
Tus nqi ntawm HEC ntxiv yuav tsum tau hloov kho raws li cov kev cai tshwj xeeb ntawm cov khoom. HEC ntau dhau yuav ua rau cov khoom khov thiab cuam tshuam rau cov neeg siv kev paub; HEC tsawg dhau yuav tsis ua tiav qhov zoo tshaj plaws thickening nyhuv. Feem ntau, tus nqi ntawm HEC siv yog nyob nruab nrab ntawm 0.5% thiab 2%, thiab yuav tsum tau hloov kho raws li cov qauv tshwj xeeb thiab cov txiaj ntsig xav tau.
3.2 Cov teeb meem solubility
HEC yuav tsum tau yaj tag nrho hauv dej kom ua haujlwm. Thaum lub sij hawm tsim khoom, HEC feem ntau yog tov nrog lwm cov khoom xyaw ua ntej maj mam ntxiv dej los tiv thaiv caking lossis agglomeration. Nyob rau tib lub sij hawm, txaus stirring yog yuav tsum tau thaum lub sij hawm dissolution los xyuas kom meej tias HEC yog tusyees dispersed nyob rau hauv cov tshuaj.
3.3 Compatibility nrog lwm cov khoom xyaw
HEC muaj qhov sib txawv ntawm cov pH sib txawv, yog li kev sib raug zoo nrog lwm cov khoom xyaw yuav tsum tau xav txog thaum tsim cov qauv. Qee cov surfactants lossis cov kuab tshuaj tuaj yeem cuam tshuam rau kev ua haujlwm ntawm HEC thiab tseem ua rau cov khoom tsis ua haujlwm. Yog li ntawd, thaum qhia cov khoom xyaw tshiab rau hauv cov mis, kev ntsuas kev ruaj ntseg txaus yuav tsum tau ua.
Daim ntawv thov ntawm hydroxyethyl cellulose hauv da dej gel thiab xab npum ua kua muaj qhov zoo. Nws tsis tsuas yog txhim kho lub cev lub zog ntawm cov khoom, tab sis kuj txhim kho cov neeg siv kev paub. Txawm li cas los xij, thaum siv HEC, kev saib xyuas yuav tsum tau them nyiaj rau kev tswj hwm ntawm qhov sib ntxiv, cov teeb meem solubility, thiab kev sib raug zoo nrog lwm cov khoom xyaw kom ntseeg tau tias muaj kev nyab xeeb thiab ua haujlwm zoo ntawm cov khoom. Nrog rau kev nce qib ntawm thev naus laus zis tsis tu ncua, daim ntawv thov kev cia siab ntawm HEC hauv cov khoom tu tus kheej yuav dav dua.
