Imibuzo emininzi ye-PEG iqala ngombuzo omnye olula: “Leliphi ixabiso lakhoPolyethylene Glycoln(PEG)?”
Njengomthengisi we-China Polyethylene Glycol kunye neminyaka ye-PEG yokubonelela ngamava, i-Dotachem ihlala ibona le meko: umthengi ucela i-PEG 400, i-PEG 6000 okanye "i-PEG ye-industrial," kodwa isicelo sokugqibela asikacaci. Emva kwemibuzo embalwa elandelayo, imfuneko yokwenene inokujika ibe yeyahlukileyo. Abanye abathengi badinga i-PEG yolwelo ukwenzela ukwakhiwa okusekwe emanzini. Abanye badinga ibakala eliqinileyo lerabha, ilaphu okanye ukwenziwa kweplastiki. Abanye badinga ibakala le-PEG elinokuthi liphumelele i-cosmetic, amayeza okanye uphononongo olunxulumene nokutya.
Yingakho iDotachem incoma ukukhetha ibakala le-PEG kwisicelo sokugqibela kuqala, endaweni yokuqala kuphela ngegama lemveliso okanye elona xabiso liphantsi.
Jonga ukuba i-PEG iya kusetyenziswa njani
Amabakala e-Polyethylene Glycol aziphatha ngendlela eyahlukileyo kuba ubunzima babo bemolekyuli buhlukile. Ekuthengeni imihla ngemihla, oku kuchaphazela amanqaku asebenzayo amaninzi: ingaba imveliso imanzi okanye iqinile, kulula kangakanani ukunyibilika, isebenza njani ngexesha lokufudumala, kwaye kufuneka ipakishwe okanye igcinwe.
Umzekelo, i-PEG 200, i-PEG 300 kunye ne-PEG 400 zidla ngokuba lula ukusingatha kwiinkqubo zamanzi. Zihlala ziqwalaselwa xa umthengi efuna ukuhambelana kakuhle kwamanzi, ukuxuba okulula okanye ukusebenza okufana ne-solvent.
I-PEG 600 kunye ne-PEG 800 zinokukhethwa xa ifomula ifuna umzimba omncinci okanye imvakalelo yokuphatha eyahlukileyo.
I-PEG 4000, PEG 6000 kunye namabakala aphezulu obunzima bemolekyuli asetyenziswa rhoqo xa kufuneka izinto eziqinileyo okanye ezifana newax. La mabanga asenokufuna ingqalelo engakumbi ngexesha lokugcinwa, ukutyisa nokuveliswa.
Ngoko ngaphambi kokukhetha ibakala le-PEG, kunceda ukubuza umbuzo osebenzayo kakhulu: ngaba le nto iya kudibaniswa kwifomula yolwelo, inyibilike ibe yinkqubo, isetyenziswe njengoncedo lokucubungula, okanye isetyenziswe njengenxalenye yesakhiwo semveliso egqityiweyo?
Yintoni abathengi abahlukeneyo abadla ngokukhathala ngayo
Amashishini awohlukeneyo awajongi i-PEG ngendlela efanayo. Apha kulapho ukhetho oluninzi olungalunganga lwenzeka khona.
Umthengi wezinto zokuthambisa unokukhathalela ivumba, umbala kunye nefuthe lokuziva ulusu. Ukuba i-PEG isetyenziswe kwikhilimu, i-cleaner, i-serum okanye i-formula ecacileyo, utshintsho oluncinci kwimbonakalo okanye iphunga liyakwazi ukubonakala kwimveliso yokugqibela.
Umthengi onxulumene namayeza udla ngokuqala kumgangatho ofunekayo kunye nenkqubo yokuvunywa. Kule meko, igama lebakala lodwa alanelanga. Imveliso kufuneka ihambelane nenkcazo yomthengi kunye neemfuno zokuphonononga ngaphambi kokuba umyalelo uqhubele phambili.
Umthengi we-textile okanye i-fiber processing unokukhathalela ngakumbi malunga nokunyibilika, isiphumo sokuthambisa, ukusebenza kwe-antistatic kunye nendlela izinto eziziphatha ngayo ngexesha lemveliso.
Umenzi werabha okanye weplastiki unokuthathela ingqalelo ukuthambisa, ukusasazwa kunye nobushushu bokulungisa. Kwaba bathengi, ibakala elifanelekileyo le-PEG linokunceda ekuphuculeni ukuphathwa, kodwa ibakala elingalunganga linokudala iingxaki zokutya okanye zokuhambelana.
Umthengi we-coating, inki okanye i-pigment system inokugxila kwi-dispersibility, impembelelo ye-viscosity kunye nokuzinza kokugcinwa.
Ulwelo lwemizi-mveliso okanye ukusetyenziswa kwesinyithi, ukuhambelana kwamanzi, ukuthambisa kunye neemeko zokusetyenzwa zidla ngokuba zibaluleke ngaphezu kokubonakala kuphela.
Kungenxa yoko le nto iDotachem ihlala ibuza malunga nesicelo ngaphambi kokucebisa ibakala le-PEG. Intsapho efanayo yemveliso inokusebenzela amashishini amaninzi, kodwa ingqiqo yokukhetha ayifani.
Indlela eSebenzayo yokucutha iBanga lePEG
Ukuba awuqinisekanga ukuba ungaqala ngaphi, le ndlela ilandelayo ikholisa ukuba luncedo kunokuthelekisa amagama emveliso kuphela.
Okokuqala, qinisekisa ifom yemveliso oyifunayo. Ukuba umgca wakho wemveliso ufuna ulwelo lwemathiriyeli ekrwada, ubunzima obusezantsi bemolekyuli iPEG kunokuba lula ukuyiphatha. Ukuba isicelo sakho sidinga izinto eziqinileyo okanye ezifana newax, ubunzima obuphezulu bemolekyuli ye-PEG inokufaneleka ngakumbi.
Okwesibini, jonga izinto eziphambili zenkcazo. Ukuthengwa kwe-PEG, abathengi bahlala befuna ukuhlaziya i-avareji ye-molecular weight, umxholo wamanzi, ixabiso le-pH, umbala, ixabiso le-hydroxyl kunye nenkangeleko. Ezinye izicelo zisenokufuna uphononongo olungqongqo.
Okwesithathu, cinga ngeemeko zemveliso. Ngaba loo nto iya kufudunyezwa? Ngaba yongezwa ngokuthe ngqo emanzini? Ngaba umzi-mveliso unezixhobo ezifanelekileyo zokugcina okanye zokutyisa? Ezi nkcukacha zinokuchaphazela ukuba ibakala likulungele na ukulisebenzisa.
Okwesine, qinisekisa isikali somyalelo. I-odolo yesampula kunye neodolo eqhelekileyo yenyanga ingafuna ukupakishwa nokucwangciswa kobonelelo.
I-Dotachem inokunceda ukuphonononga ezi nkcukacha ngaphambi kokucaphula, ngoko abathengi akufuneki bakhethe kuphela ngegama lebakala.
Iimpazamo eziqhelekileyo ezenziwa ngabathengi xa bekhetha i-PEG
Enye impazamo eqhelekileyo kukuphatha amabanga ePEG njengento etshintshanayo. I-PEG 400 kunye ne-PEG 6000 zombini i-Polyethylene Glycol, kodwa ayisetyenziswanga ngendlela efanayo. Bahluke kwifom, i-viscosity, ukuziphatha okunyibilikayo kunye nokuphatha. Ukutshintsha elinye ibakala ulifake kwelinye ngaphandle kovavanyo kunokuchaphazela ifomyula okanye inkqubo yokuvelisa.
Enye impazamo kukujonga ixabiso ngaphambi kokujonga iinkcukacha. Ibakala le-PEG elinexabiso eliphantsi alisoloko linexabiso eliphantsi xa libangela uvavanyo kwakhona, uhlengahlengiso lwefomula okanye ukulibaziseka kwemveliso.
Abanye abathengi baphinda bawuhoye umxholo wamanzi kunye nexabiso le-pH. Ezi zinto zinokujongeka zincinci kwiphepha elichaziweyo, kodwa zinokubaluleka kwizinto zokuthambisa, iingubo, izinto ezincedisayo zamalaphu, iimveliso ezinxulumene namayeza kunye nolunye usetyenziso olusekwe kwifomula.
Amaxwebhu yenye ingongoma esoloko iqinisekiswa emva kwexesha. Ukuba ayafuneka i-COA, i-MSDS, i-TDS okanye amanye amaxwebhu okuvunywa kwemvume, kubhetele ukukhankanya oku ngexesha lesigaba sophando, kungabi emva kokuba kulungiselelwa ukuthunyelwa.
Ukupakishwa kusenokubangela iingxaki. I-PEG yolwelo kunye ne-PEG eqinileyo ayiphathwa ngendlela efanayo. Iigubhu, iingxowa, ii-IBCs okanye ezinye iipakethe kufuneka zikhethwe ngokwefom yemveliso, ubungakanani beodolo kunye neemeko zokuthuthwa kwefektri.
Loluphi ulwazi onokuthi uluthumele kuMboneleli wePEG?
Ukufumana ikowuti ekhawulezayo nechanekileyo, abathengi banokulungiselela ezimbalwaiinkcukachangaphambi kokuqhagamshelana neDotachem:
Ngolu lwazi, iDotachem inokukhangela i-PEG inketho efanelekileyo, amaxwebhu akhoyo, indlela yokupakisha kunye nesicwangciso sokuhambisa ngokukhawuleza.
I-Dotachem inceda njani abathengi baphephe ukukhetha okungalunganga kwe-PEG
