Ukusetyenziswa kwe-Hydroxyethyl Cellulose (HEC)

I-Hydroxyethyl Cellulose (HEC) i-polymer e-soluble yamanzi esetyenziswa ngokubanzi kwiintlobo ezahlukeneyo zezicelo ngenxa yeempawu zayo ezizodwa. I-HEC ithathwe kwi-cellulose kwaye isetyenziswa ngokuqhelekileyo njenge-ejenti yokuqina, ukuzinzisa, kunye ne-rheology-modifying agent kumashishini ahlukeneyo.HEC i-polymer eguquguqukayo kunye noluhlu olubanzi lwezicelo ngenxa yeempawu zayo ezikhethekileyo, ezifana nokunyibilika kwamanzi, ukuqina kunye izakhono zokuzinzisa, kunye neempawu zokuguqula i-rheology. Ukuguquguquka kwayo kunye nokusebenziseka ngokulula kuyenza ibe lukhetho oludumileyo kumashishini ahlukeneyo, kubandakanya ipeyinti & ukugquma, ukhathalelo lomntu, ulwakhiwo, ukutya, amayeza, ioyile negesi, iphepha, kunye namalaphu.

●Ipeyinti neCoating thickener

Ipeyinti yelatex equlatheI-HECicandelo lineempawu zokuchithwa ngokukhawuleza, igwebu eliphantsi, isiphumo esihle sokuqina, ukwandiswa kombala okulungileyo kunye nokuzinza ngakumbi. Iimpawu zayo ezingenayo i-ionic zinceda ukuzinzisa phezu koluhlu olubanzi lwe-pH kwaye uvumele uluhlu olubanzi lokuqulunqa.

Ukusebenza okuphezulu kweemveliso ze-HEC HS kukuba i-hydration inokulawulwa ngokudibanisa i-thickener emanzini ekuqaleni kokugaya i-pigment.

Amabanga aphezulu e-viscosity ye-HEC HS100000, HEC HS150000 kunye ne-HEC HS200000 aphuhliselwe ubukhulu becala ukuveliswa kwepeyinti yelatex enyibilikayo emanzini, kwaye idosi incinci kunezinye i-thickeners.

●Ezolimo

I-Hydroxyethyl cellulose (HEC) inokunqumamisa ngokufanelekileyo iityhefu eziqinileyo kwizitshizi ezisekwe emanzini.

Ukusetyenziswa kwe-HEC ekusebenzeni kokutshiza kunokudlala indima yokubambelela kwityhefu kwindawo yeqabunga; I-HEC ingasetyenziswa njenge-thickener ye-emulsion yokutshiza ukunciphisa ukukhukuliseka kweyeza, ngokwenjenjalo ukwandisa isiphumo sokusebenzisa isitshizi se-foliar.

I-HEC isenokusetyenziswa njenge-ejenti yokwenza ifilimu kwii-agent zokugquma imbewu; njengesibophelelo ekusetyenzisweni ngokutsha kwamagqabi ecuba.

● Izinto zokwakha

I-HEC ingasetyenziselwa i-gypsum, i-samente, i-lime kunye neenkqubo zodaka, i-tile paste kunye nodaka. Kwicandelo le-samente, linokusetyenziswa njenge-retarder kunye ne-arhente yokugcina amanzi. Kunyango oluphezulu lwemisebenzi ye-siding, isetyenziswe ekuqulunqweni kwe-latex, enokuthi iphathe kwangaphambili i-surface kwaye ikhulule uxinzelelo eludongeni, ukwenzela ukuba umphumo wokupenda kunye nokugubungela umphezulu ube ngcono; inokusetyenziswa njenge-thickener yokuncamathelisa iphepha lodonga.

I-HEC inokuphucula ukusebenza kwe-gypsum mortar ngokunyusa ukuqina kunye nexesha lesicelo. Ngokubhekiselele kumandla oxinzelelo, amandla e-torsional kunye nokuzinza kwe-dimensional, i-HEC inefuthe elingcono kunezinye iiselulosi.

●Izinto zokuthambisa kunye nezokucoca

I-HEC yifilimu esebenzayo yangaphambili, i-binder, i-thickener, i-stabilizer kunye ne-dispersant kwii-shampoos, izitshizi zeenwele, i-neutralizers, i-conditioners kunye ne-cosmetics. Ukuqina kwayo kunye neepropathi ze-colloid ezikhuselayo zingasetyenziselwa kumashishini olwelo kunye ne-detergent. I-HEC ichithwa ngokukhawuleza kwiqondo lokushisa eliphezulu, elinokukhawuleza inkqubo yokuvelisa kunye nokuphucula ukusebenza kakuhle kwemveliso. Kuyaziwa ukuba uphawu olwahlukileyo lwezokucoca eziqulethe i-HEC kukuphucula ukuguda kunye ne-mercerization yamalaphu.

●Latex polymerization

Ukukhetha i-HEC ngeqondo elithile lokutshintshwa kwe-molar kunokudlala umphumo ongcono kakhulu kwinkqubo yokwenza i-polymerization ye-colloids ekhuselayo; ekulawuleni ukukhula kweengqungquthela ze-polymer, ukuzinzisa ukusebenza kwe-latex, kunye nokuchasana nokushisa okuphantsi kunye nokushisa okuphezulu, kunye nokucheba ngoomatshini, i-HEC ingasetyenziswa. ngeyona mpembelelo ilungileyo. Ngexesha le-polymerization ye-latex, i-HEC inokukhusela ukuxinwa kwe-colloid ngaphakathi koluhlu olubalulekileyo, kunye nokulawula ubungakanani beengqungquthela ze-polymer kunye neqondo lenkululeko yamaqela asebenzayo athatha inxaxheba.

● Ukukhutshwa kwepetroleum

I-HEC ijongana nokusebenza kunye nokuzalisa i-slurries. Inceda ukubonelela ngodaka oluqinileyo olusezantsi kunye nomonakalo omncinci kumthombo. I-Slurry egqitywe nge-HEC iyancipha ngokulula kwi-hydrocarbons nge-acids, i-enzymes okanye i-oxidants kwaye yandisa ukubuyiswa kweoli.

Kudaka oluqhekekileyo, i-HEC inokudlala indima yokuthwala udaka kunye nesanti. Olu lwelo lusenokonakaliswa lula zezi asidi ezingentla, ii-enzymes okanye ii-oxidants.

I-solid low low drilling fluid inokuqulunqwa kunye ne-HEC, ebonelela ngokugqithiseka okukhulu kunye nokuzinza okungcono kokomba. Iimpawu zayo zokugcina ulwelo zinokusetyenziswa ekwembeni amatye aqinileyo kunye nakwimibhobho edilikayo.

Emsebenzini wokongeza i-cement, i-HEC inciphisa ukuxhathisa i-frictional ye-pore-pressure sement slurry, ngaloo ndlela inciphisa umonakalo kwisakhiwo esibangelwa ukulahlekelwa kwamanzi.

● Iphepha ne-inki

I-HEC ingasetyenziselwa njenge-ejenti yokubeka iphepha kunye nekhadibhodi kunye neglue ekhuselayo ye-inki. I-HEC inenzuzo yokuzimela ngobungakanani bephepha ekushicileleni, kwaye ingasetyenziselwa ukuprinta imifanekiso ephezulu, kwaye ngexesha elifanayo, inokunciphisa iindleko ngenxa yokungena kwayo okuphantsi kunye ne-gloss enamandla.

Isenokusetyenziswa kulo naliphi na isayizi yephepha okanye ikhadibhodi yoshicilelo okanye ikhalenda yoshicilelo. Kwisilinganisi sephepha, idosi yayo eqhelekileyo yi-0.5 ~ 2.0 g/m2.

I-HEC inokunyusa ukusebenza kokugcinwa kwamanzi kwimibala yepeyinti, ngakumbi iipeyinti ezinomlinganiselo ophezulu welatex.

Kwinkqubo yokwenza iphepha, i-HEC inezinye iipropathi eziphezulu, kubandakanywa ukuhambelana neentsini ezininzi, i-resin kunye neetyuwa ze-inorganic, i-solubility esheshayo, i-foaming ephantsi, ukusetyenziswa kwe-oksijini ephantsi kunye nokukwazi ukwenza ifilimu epholileyo.

Kwimveliso ye-inki, i-HEC isetyenziselwa ukuveliswa kwee-inki zekopi ezisekelwe emanzini ezomileyo ngokukhawuleza kwaye zisasazeke kakuhle ngaphandle kokunamathela.

●Ubungakanani belaphu

I-HEC kudala isetyenziswa ekulinganiseni nasekudayeni imisonto kunye nemathiriyeli yelaphu, kwaye iglu inokukhukuliswa kude nemicu ngokuhlamba ngamanzi. Ngokudibanisa nezinye iirasi, i-HEC inokusetyenziswa ngokubanzi kunyango lwelaphu, kwi-fiber yeglasi isetyenziswe njenge-agent agent kunye ne-binder, kunye ne-pulp yesikhumba njenge-modifier kunye ne-binder.

Iingubo ze-latex zelaphu, i-adhesives kunye ne-adhesives

Izincamathelisi ezityetyisiweyo nge-HEC ziyi-pseudoplastic, oko kukuthi, zibhityile phantsi kwe-chear, kodwa zibuyela ngokukhawuleza kulawulo lwe-viscosity ephezulu kunye nokuphucula ukucaca koshicilelo.

I-HEC inokulawula ukukhutshwa komswakama kwaye ivumele ukuba iqhube ngokuqhubekayo kwi-dayi roll ngaphandle kokufaka i-adhesive. Ukulawula ukukhutshwa kwamanzi kuvumela ixesha elingakumbi elivulekileyo, elinenzuzo yokuqulathwa kokuzalisa kunye nokwakhiwa kwefilimu engcono yokubambelela ngaphandle kokwandisa kakhulu ixesha lokumisa.

I-HEC HS300 kwi-concentration ye-0.2% ukuya kwi-0.5% kwisisombululo iphucula amandla omatshini we-adhesives non-woven adhesives, ukunciphisa ukucocwa okumanzi kwimiqulu emanzi, kunye nokwandisa amandla amanzi emveliso yokugqibela.

I-HEC HS60000 yeyona nto incamathelayo ukuprinta kunye nokudaya amalaphu angalukwanga, kwaye inokufumana imifanekiso ecacileyo, emihle.

I-HEC ingasetyenziswa njenge-binder yeepeyinti ze-acrylic kunye ne-adhesive ye-non-woven processing. Ikwasetyenziswa njenge-thickener ye-primers yelaphu kunye ne-adhesives. Ayiphenduli kunye nezihluzi kwaye ihlala isebenza kakuhle kwiindawo eziphantsi.

Ukudaywa kunye nokuprintwa kweekhaphethi zelaphu

Kwikhaphethi yokudaya, njengenkqubo ye-Kusters eqhubekayo yokudaya, ezinye izinto ezityebileyo ezimbalwa zinokuhambelana nefuthe lokutyeba kunye nokuhambelana kwe-HEC. Ngenxa yesiphumo esihle sokutyeba, inyibilika ngokulula kwizinyibilikisi ezahlukeneyo, kwaye umxholo wayo ophantsi wokungcola awuphazamisi ukufunxwa kwedayi kunye nokusasazwa kombala, ukwenza ushicilelo kunye nokudaya simahla kwiigels ezinganyibilikiyo (ezinokubangela amabala kumalaphu) kunye nemida yeHomogeneity iimfuno eziphezulu zobugcisa.
