IHydroxyethyl Cellulose (HEC) iyi-polymer encibilika emanzini esetshenziswa kabanzi ezinhlelweni ezihlukene ngenxa yezakhiwo zayo ezihlukile. I-HEC itholakala ku-cellulose futhi ivame ukusetshenziswa njenge-ejenti yokuqina, ukuzinzisa, kanye ne-rheology-modifying ezimbonini ezihlukahlukene.I-HEC iyi-polymer eguquguqukayo enezinhlobonhlobo zezicelo ngenxa yezakhiwo zayo eziyingqayizivele, njengokuncibilika kwamanzi, ukuqina kanye amakhono okuzinzisa, kanye nezakhiwo zokuguqula i-rheology. Ukusebenziseka kwayo ngezindlela eziningi kanye nokusebenziseka kalula kwayo kuyenza ibe yisinqumo esidumile ezimbonini ezahlukahlukene, okuhlanganisa upende&ukunamathela, ukunakekela komuntu siqu, ukwakhiwa, ukudla, imithi, uwoyela negesi, iphepha, nezindwangu.
●I-Paint&Coating thickener
Upende we-latex oquketheI-HECingxenye inezindawo zokuqedwa ngokushesha, igwebu eliphansi, umphumela omuhle wokujiya, ukunwetshwa kombala omuhle nokuzinza okwengeziwe. Izici zayo ezingezona i-ionic zisiza ukuzinza phezu kwebanga elibanzi le-pH futhi zivumele ukwakheka okubanzi.
Ukusebenza okuphezulu kwemikhiqizo yochungechunge lwe-HEC HS ukuthi i-hydration ingalawulwa ngokungeza i-thickener emanzini ekuqaleni kokugaya i-pigment.
Amabanga aphezulu e-viscosity e-HEC HS100000, HEC HS150000 kanye ne-HEC HS200000 athuthukiswa kakhulu ukuze kukhiqizwe opende be-latex abancibilika emanzini, futhi umthamo mncane kunezinye izingqimba.
●Ezolimo
IHydroxyethyl cellulose (HEC) ingamisa ngempumelelo ubuthi obuqinile kuzifutho ezisekelwe emanzini.
Ukusetshenziswa kwe-HEC ekusebenzeni kwesifutho kungadlala indima yokunamathela ubuthi endaweni yamaqabunga; I-HEC ingasetshenziswa njenge-thickener ye-emulsion yesifutho ukunciphisa ukukhukhuleka komuthi, ngaleyo ndlela kwandise umphumela wokusetshenziswa kwesifutho se-foliar.
I-HEC ingasetshenziswa futhi njenge-ejenti eyenza ifilimu kuma-ejenti okugcoba imbewu; njengesibopho ekugayweni kabusha kwamaqabunga kagwayi.
●Izinto zokwakha
I-HEC ingasetshenziswa kumasistimu we-gypsum, usimende, umcako nodaka, unamathisele amathayili nodaka. Engxenyeni kasimende, ingasetshenziswa futhi njenge-retarder kanye ne-ejenti yokugcina amanzi. Ekwelapheni okungaphezulu kokusebenza kwe-siding, isetshenziselwa ukwakhiwa kwe-latex, engakwazi ukwelapha ngaphambili futhi ikhulule ukucindezelwa kodonga, ukuze umphumela wokudweba nokugqoka phezulu kube ngcono; ingasetshenziswa njenge-thickener ye-adhesive yamaphephadonga.
I-HEC ingathuthukisa ukusebenza kwe-gypsum mortar ngokukhulisa ukuqina kanye nesikhathi sokufaka isicelo. Mayelana namandla acindezelayo, amandla e-torsional kanye nokuzinza kwe-dimensional, i-HEC inomphumela ongcono kunamanye ama-cellulose.
●Izimonyo nezihlanzi
I-HEC iyifilimu esebenzayo yangaphambili, i-binder, thickener, stabilizer kanye ne-dispersant kuma-shampoos, izifutho zezinwele, ama-neutralizers, ama-conditioner nezimonyo. Izakhiwo zayo eziqinile nezivikelayo ze-colloid zingasetshenziswa ezimbonini zokuhlanza eziwuketshezi neziqinile. I-HEC incibilika ngokushesha ekushiseni okuphezulu, okungasheshisa inqubo yokukhiqiza futhi kuthuthukise ukusebenza kahle kokukhiqiza. Kuyaziwa ukuthi isici esihlukile sezinto zokuhlanza eziqukethe i-HEC ukuthuthukisa ukushelela kanye ne-mercerization yezindwangu.
● I-Latex polymerization
Ukukhetha i-HEC ene-molar substitution degree ethile ingadlala umphumela omuhle kakhulu enqubweni yokwenza i-polymerization yama-colloid avikelayo; ekulawuleni ukukhula kwezinhlayiya ze-polymer, ukuzinzisa ukusebenza kwe-latex, nokumelana nokushisa okuphansi nokushisa okuphezulu, nokugunda kwemishini, i-HEC ingasetshenziswa. kube nomphumela omuhle kakhulu. Ngesikhathi se-polymerization ye-latex, i-HEC ingavikela ukugxila kwe-colloid ngaphakathi kwebanga elibucayi, futhi ilawule ubukhulu bezinhlayiya ze-polymer kanye nezinga lenkululeko yamaqembu asebenzayo abamba iqhaza.
● Ukukhishwa kukaphethiloli
I-HEC imatasatasa ekucubunguleni nasekugcwaliseni ama-slurries. Isiza ukuhlinzeka ngodaka oluhle oluqinile olunomonakalo omncane emgodini womthombo. I-slurry egqinswe nge-HEC yehliswa kalula ibe ama-hydrocarbon ngama-acids, ama-enzyme noma ama-oxidants futhi kukhulisa ukutholakala kukawoyela.
Odakeni oluphukile, i-HEC ingadlala indima yokuthwala udaka nesihlabathi. Lawa manzi angonakaliswa kalula yilawa ma-asidi angenhla, ama-enzyme noma ama-oxidant.
Uketshezi lokumba oluqinile olusezingeni eliphansi lungakhiwa nge-HEC, olunikeza ukungeneka okukhulu kanye nokuzinza okungcono kokumba. Izakhiwo zayo ezigcina uketshezi zingasetshenziswa ekubhobozeni amatshe aqinile kanye nama-slump noma ama-slump shale formations.
Ekusebenzeni kokwengeza usimende, i-HEC inciphisa ukumelana nokungqubuzana kwe-pore-pressure Cement slurry, ngaleyo ndlela inciphise umonakalo esakhiweni esibangelwa ukulahlekelwa kwamanzi.
● Iphepha noyinki
I-HEC ingasetshenziswa njenge-ejenti ecwebezelayo yephepha nekhadibhodi kanye neglue yokuvikela uyinki. I-HEC inenzuzo yokuzimela ngosayizi wephepha ekunyatheliseni, futhi ingasetshenziselwa ukuphrinta izithombe zekhwalithi ephezulu, futhi ngesikhathi esifanayo, inganciphisa izindleko ngenxa yokungena kwayo okuphansi nokucwebezela okuqinile.
Ingasetshenziswa futhi kunoma yimuphi usayizi wephepha noma ukuphrinta kwekhadibhodi noma ukuphrinta kwekhalenda. Ekulinganisweni kwephepha, umthamo walo ojwayelekile ngu-0.5 ~ 2.0 g/m2.
I-HEC ingakhuphula ukusebenza kokulondoloza amanzi ngemibala kapende, ikakhulukazi opende abanengxenye ephezulu ye-latex.
Enqubweni yokwenza iphepha, i-HEC inezinye izakhiwo eziphakeme, okuhlanganisa ukuhambisana nezinsini eziningi, ama-resin kanye nosawoti we-inorganic, ukuncibilika okusheshayo, ukugwedla okuphansi, ukusetshenziswa okuphansi kwe-oxygen kanye nekhono lokwenza ifilimu elibushelelezi elingaphezulu.
Ekwenziweni kukayinki, i-HEC isetshenziswa ekukhiqizeni iziyinki zamakhophi asekelwe emanzini ezomisa ngokushesha futhi zisakazeke kahle ngaphandle kokunamathela.
●Ukulinganisa kwendwangu
Sekuyisikhathi eside i-HEC isetshenziswa ekulinganisweni nasekudayeni intambo nempahla yendwangu, futhi ingcina ingakhukhulwa isuke emicu ngokuwasha ngamanzi. Ngokuhlanganiswa namanye ama-resin, i-HEC ingasetshenziswa kabanzi ekwelapheni indwangu, ku-fiber yengilazi isetshenziswa njenge-ejenti yokwakha kanye ne-binder, kanye ne-pulp yesikhumba njenge-modifier ne-binder.
Izindwangu ze-latex zendwangu, ama-adhesives nama-adhesives
Izinamathiselo ezigqinsiwe nge-HEC ziyi-pseudoplastic, okungukuthi, zincane ngaphansi kwe-shear, kodwa zibuyela ngokushesha ekulawuleni i-viscosity ephezulu futhi zithuthukise ukucaca kokuphrinta.
I-HEC ingakwazi ukulawula ukukhishwa komswakama futhi ivumele ukuthi igeleze ngokuqhubekayo ku-dayi roll ngaphandle kokwengeza i-adhesive. Ukulawula ukukhululwa kwamanzi kuvumela isikhathi esiningi esivulekile, esizuzisa ukuqukatha kokugcwalisa kanye nokwakhiwa kwefilimu yokunamathisela engcono ngaphandle kokwandisa kakhulu isikhathi sokumisa.
I-HEC HS300 ekuhlanganiseni kuka-0.2% kuya ku-0.5% esixazululweni ithuthukisa amandla emishini yezinto ezinamathelayo ezingalukiwe, inciphisa ukuhlanzwa okumanzi kumaroli amanzi, futhi yandise amandla amanzi omkhiqizo wokugcina.
I-HEC HS60000 iyingcina efanelekile yokuphrinta nokudaya izindwangu ezingalukiwe, futhi ingathola izithombe ezicacile, ezinhle.
I-HEC ingasetshenziswa njengesibophezelo sikapende we-acrylic nanjenge-adhesive yokucubungula okungalukiwe. Ibuye isetshenziswe njenge-thickener ye-primers yendwangu kanye nama-adhesives. Ayisabeli ngama-fillers futhi ihlala isebenza kahle ekugxilweni okuphansi.
Ukudaya nokuphrinta okhaphethi bendwangu
Ekudayeni ukhaphethi, njengesistimu yokudaya eqhubekayo ye-Kusters, ezinye izinto eziwugqinsi ezimbalwa zingafanisa umphumela wokujiya nokuhambisana kwe-HEC. Ngenxa yomphumela wayo omuhle wokujiya, uncibilika kalula ezincibilikisini ezihlukahlukene, futhi okuqukethwe kwawo kokungcola okuphansi akuphazamisi ukumuncwa kodayi nokusabalaliswa kombala, okwenza ukuphrinta nokudaya kungabi nama-gel angancibiliki (okungabangela amachashazi ezindwangu) kanye nemingcele ye-Homogeneity izidingo zobuchwepheshe eziphezulu.
