Iziphumo ze-hydroxythl seluplose yongeziweyo kwintsebenzo yenkqubo yepeyinti ye-Latex

I-HYDROXYTYL ILANDILONE (Hec)Ngaba i-tickener, i-stabilizer kunye ne-Rheology isetyenziswa rhoqo kwipende ye-Latex. Yinto eqingqiweyo ye-polymer ye-polymer afunyenwe yindlela ye-hydroxyyteythy paillese yendalo, enomoya ofanelekileyo wamanzi, ongenabuthathaka kunye nokukhusela kwendalo. Njengenxalenye ebalulekileyo yepeyinti ye-REEX, indlela eyongeziweyo ye-hydroxyyteethl seluplose ichaphazela ngokuthe ngqo iipropathi ze-rihlooing, ukusebenza, ukuzinza, ixesha lokwenza, izinto ezomisayo kunye nezinye izinto eziphambili zepeyinti ye-Latex.

I-1. Indlela yokusebenza ye-hydroxyythl seluplose

Imisebenzi ephambili ye-hydroxythyl seluplose kwinkqubo yepeyinti ye-Latex ibandakanya:

Ukutyibilika kunye nokuzinza: Amaqela e-hydroxyyl kwi-hec molecular thein ye-hydrogen ye-hydrogen enemolekyuli yamanzi, eyenza ipeyinti yenkqubo kwaye yenza ukuba ipeyinti ye-testx ineempawu ezintle. Ikwandise uzinzo lwepeyinti ye-Feex kwaye kuthintela ukuntywila kwe-pigments kunye neefilitha ngokusebenzisana nezinye izithako.

Ummiselo we-RTOIL: I-HEC inokuhlengahlengisa iipropathi ze-RIOOOOOOLOTER yepeyinti ye-REEX kwaye iphucule ukumiswa kunye nokudibana kwepeyinti yepeyinti. Phantsi kweemeko ezahlukeneyo zeshera, i-HEC inokubonisa ulwalamano olwahlukileyo, ngakumbi kumaxabiso asezantsi asezantsi, inokunyusa i-viscofity yepeyinti, ukuthintela ukulingana, kunye nokuqinisekisa ukufana kwepeyinti.

Ukugcinwa kwe-hydration kunye ne-hydration ye-hec kwipeyinti ye-Latex ayinakuphela nje ukwandisa i-viscofity yayo kuphela, kodwa ikwandisa ixesha elomileyo lefilimu yepeyinti, kwaye inciphise ukusebenza kakuhle kwepeyinti ngexesha lolwakhiwo.

2.

Indlela yongezelelo yeHecinefuthe elibalulekileyo kwintsebenzo yokugqibela yepeyinti ye-Latex. Iindlela zokudibanisa eziqhelekileyo zibandakanya indlela yokudibanisa ngokuthe ngqo, indlela yokuphelisa kunye nendlela yokusasaza, kwaye indlela nganye inezibonelelo ezahlukeneyo nezingalunganga.

2.1 Indlela yoMsebenzi

Indlela yokuvunywa ngokuthe ngqo kukongeza i-Hydroxythyl ngqo kwinkqubo yepeyinti ye-Fetex, kwaye ihlala ifuna ukuvuselela okwaneleyo ngexesha lokuxuba. Le ndlela ilula kwaye ilula ukusebenza, kwaye ilungele ukuveliswa kwepeyinti ye-Latex. Nangona kunjalo, xa uyongezwa ngokuthe ngqo, ngenxa yamasuntswana amakhulu e-hec, kunzima ukunyibilikisa ngokukhawuleza, oko kunokubangela ukungavisisani, okuchaphazela ukuthembeka okufanayo kunye ne-rothoology yepeyinti ye-upex. Ukwenzela ukunqanda le meko, kuyimfuneko ukuqinisekisa ixesha elaneleyo lokukhulisa kunye neqondo lobushushu elifanelekileyo ngexesha lokukhuthaza ukuchitheka kunye nokusasazwa kwe-hec.

2.2 Indlela yokuphelisa

Indlela yokuchithwa kukuchitha i-hec emanzini ukwenza isisombululo esihlanganisiweyo, kwaye yongeza isisombululo kwipeyinti ye-latex. Indlela yokuhlulela inokuqinisekisa ukuba i-HEC ichithwe ngokupheleleyo, kuphephe ingxaki ye-sublomeration, kunye nokwenza ukuba i-hec isasazwe ngokulinganayo kwindima ka-Latex, idlala indima yohlengahlengiso oluhle kunye nelazi. Le ndlela ifanelekile kwiimveliso zepeyinti eziphezulu ezifuna uzinzo lwepeyinti ephezulu kunye neepropathi ze-friclocal. Nangona kunjalo, inkqubo yokuphelisa ithatha ixesha elide kwaye ineemfuno eziphezulu zokufumana isantya kunye neqondo lokuhlaselwa.

2.3 Indlela yokusasaza

Indlela yokusasaza ixube i-hec kunye nezinye iisoyile okanye izinyibilikisi kwaye isasaza izixhobo eziphezulu zokusasazeka kweShear ukwenza i-hec yepeyinti. Indlela yokusasazeka inokuphepha ngokufanelekileyo ukwahlukaniswa kwe-HEC, igcine uzinzo lwesakhiwo sayo semolekyuli, kwaye siphucule ipropathi ye-RIOOIL kunye nokuxubha kwepeyinti ye-templex. Indlela yokusasazeka ilungele imveliso enkulu, kodwa ifuna ukusetyenziswa kwezixhobo zokusasazeka kwengcali, kwaye ulawulo lobushushu kunye nexesha lenkqubo yokusasazeka ingqongqo.

I-3. Isiphumo se-hydroxythyl seluplose yongezwa kwi-Latex Pepet Peet

Iindlela ezahlukeneyo zokuvumela i-HeC ziya kuchaphazela ngqo le mibala ilandelayo yepeyinti ye-Latex:

3.1 Iipropathi ze-ROOOOOOLORTE

Iipropathi ze-ROOOOLOTERHecsisiphawuli sentsebenzo yepeyinti ye-Latex. Ngokufunda ngeendlela zokuvumela ihek, kwafunyaniswa ukuba indlela yokuchithwa kunye nendlela yokusasazeka inokuphucula iipropathi ze-RIOOOIL yepeyinti yokupeyinta i-testax ngaphezulu kwendlela eyahlukileyo. Kuvavanyo lwendalo, indlela yokuchithwa kunye nendlela yokusasazeka kunye nendlela yokusasazeka inokuphucula ipeyinti ye-Latex kwi-Sheet ye-Sheart kwi-Sheart ye-Shear kwi-Peest kunye nepeyinti ye-Fedex, kwaye inokuthintela i-pronomenon yenkqubo yokwakha.

3.2 Uzinzo

Indlela yodliwano-vic ye-hec inesiphumo esibonakalayo ekuzinzo kwepeyinti ye-latex. Ipeyinti ye-Latex usebenzisa indlela yokuchithwa kunye neendlela zokusasazeka zihlala zizinzile kwaye zinokuthintela ngokufanelekileyo ukuntywila kunye neefilitha. Indlela yokomoya ethe ngqo ithathela ingqalelo ukusasazeka ngokungalingani, nto leyo ichaphazela uzinzo lwepeyinti, kwaye ityekele kwi-sediment kunye nokuxhaphaka, ukunciphisa ubomi benkonzo yepeyinti.

3.3 IPREATRTE ZOKUGQIBELA

Iipropathi zokudibana kubandakanya ukupapashwa, ukugubungela amandla kunye nobungqingqwa bokuphazamiseka. Emva kokuba kwenzeke into yokuchithwa kunye nendlela yokusasazeka, ukuhanjiswa kwe-ICC kuninzi kakhulu, nto leyo inokulawula ngokuphumelelayo ukungqubana kunye nokwenza ukuba i-cariding ibonakalise ukuba nenqanaba elifanelekileyo kunye ne-adhesions ngexesha lenkqubo yokuhlela. Enye indlela eyongezwe ngokuthe ngqo inokubangela ukuhanjiswa okungalinganiyo kwamasuntswana, nto leyo ichaphazela indlela yokusebenza.

3.4 ixesha lokukomisa

Ukugcinwa kwamanzi kwe-hec ye-hec kunefuthe elibalulekileyo kwiphepha elomileyo lepeyinti ye-latex. Indlela yokuchithwa kunye nendlela yokusasazeka inokuthi ngcono kummangalela kwipeyinti ye-Latex, ikhulisa ixesha lokumisa, kwaye incede ukunciphisa i-phenomeno yomile kakhulu kwaye iqhekeze ngexesha lokuqalisa. Eyona ndlela yokuvunywa ngokuthe ngqo inokubangela ukuba ezinye i-hec ichithwe kakhulu, ngaloo ndlela ichaphazela ukufana okuko okomileyo kunye nokudibana komgangatho wokupeyinta.

I-4. Iingcebiso zokuphumelela

Iindlela ezahlukeneyo zokongezahydroxyyl seluploseYiba nefuthe elibonakalayo kwintsebenzo yenkqubo yepeyinti ye-Fetex. Indlela yokuchitha kunye nendlela yokusasazeka ineziphumo ezingcono kunendlela yokuvunywa ngokuthe ngqo, ngakumbi ekuphuculeni iipropathi zeRhemoological, uzinzo kunye nokusebenza komsebenzi. Ukwenzela ukuba kube lula ukusebenza kwepeyinti ye-REEX, kuyacetyiswa ukuba isebenzise indlela yokuphelisa okanye indlela yokusasazwa ngexesha lenkqubo yokuqinisekisa ukuchithwa okupheleleyo kunye nokusasazeka kwe-HEC, ngaloo ndlela kuphucule ipeyinti epheleleyo yepeyinti.

Kwimveliso yokwenyani, indlela efanelekileyo yongezelelo ye-hec kufuneka ikhethwe ngokwefomula ye-upebx, kunye nesi siseko, ukushukumisa, ukunyibilika kunye nokusasaza iinkqubo zepeyinti.
