Liaparo tsa ka ntle li phetha karolo ea bohlokoa ho sireletsa mehaho ho tloha likarolong tsa tikoloho, ho fana ka boipiletso bo botle le ho netefatsa hore e tšoarella nako e telele.Re shebisisa litšobotsi tsa li-cellulose ethers, karolo ea tsona e le li-thickeners le rheology modifiers, le phello ea li-additives ho thepa e kang ho khomarela, boemo ba leholimo, le ho tšoarella ha moaparo ka kakaretso.Bakeng sa baetsi ba lihlahisoa le bahlahisi ba ikemiselitseng ho etsa liaparo tsa boleng bo holimo tsa bokantle, kutloisiso e felletseng ea metsoako ena e bohlokoa.
tsebisa:
Ho roala ka ntle ho bohlokoa ho sireletsa meaho maemong a leholimo a mabe, mahlaseli a UV, litšila le lintho tse ling tsa tikoloho.Li-cellulose ethers tse tsoang mehloling ea tlhaho ea cellulose le mefuta e mengata ea li-additives li kenya letsoho haholo ntlafatsong ea liphahlo tsena.
Li-cellulose ethers tse ka ntle tsa lebota:
2.1.Kakaretso ea li-cellulose ethers:
Li-cellulose ethers li kenyelletsa methylcellulose (MC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), carboxymethylcellulose (CMC), joalo-joalo, tse sebelisoang haholo lits'ebetsong tsa ka ntle ka lebaka la thepa ea tsona e ikhethang.Ka pente ea lebota.Li-polymer tsena li sebetsa joalo ka li-thickeners, li-binders, le li-addifiers tsa rheology, tse fanang ka liphahlo ka thepa ea tsona ea bohlokoa.
2.2.Thickening properties:
Li-cellulose ethers ke li-thickeners tse sebetsang hantle tse eketsang viscosity ea liphahlo, li khothaletsa ts'ebeliso e ntle le ho fokotsa ho fokotseha.Sebopeho sa limolek'hule tsa cellulose ethers ha se na metsi, se netefatsa hore ho na le viscosity e nepahetseng le ho lumellana ha kopo.
2.3.Phetoho ea Rheological:
Ho laola boitšoaro ba rheological ba liaparo tsa ka ntle ho bohlokoa ho finyella thepa e lakatsehang ea kopo.Li-cellulose ethers li phetha karolo ea bohlokoa ho fetoleng rheology ea liphahlo, ho ntlafatsa phallo ea tsona le ho leka-lekanya thepa.Sena se etsa hore ho be bonolo ho sebelisa le ho etsa hore ho be le botenya ba seaparo se tšoanang.
Li-additives tsa ho ntlafatsa pente ea ka ntle:
3.1.Adhesion promoter:
Ho khomarela ke ntho e ka sehloohong e amang ts'ebetso ea marako a ka ntle a marako.Li-additives tse fapaneng, joalo ka li-silane le li-polymer tsa acrylic, li ntlafatsa ho khomarela ka ho holisa maqhama a matla lipakeng tsa ho roala le substrate.Sena se tiisa ho tšoarella ha nako e telele le ho hanyetsa ho ebola kapa ho phatloha.
3.2.Li-additives tsa boemo ba leholimo:
Pente e ka ntle e pepesetsoa maemo a leholimo a fapaneng, ho kenyelletsa khanya ea letsatsi, pula, le ho fetoha ha mocheso.Li-stabilizer tsa UV, li-stabilizer tsa amine tse thibelang (HALS), le li-additives tse ling tsa boemo ba leholimo li sireletsa likhoele ho senyeha ho bakoang ke mahlaseli a UV le lits'ebetso tsa oxidation, ka hona, li lelefatsa bophelo ba tsona ba ts'ebeletso.
3.3.Li-antifungal le li-antimicrobial agents:
Libaka tse ka ntle li ka ba bonolo ho kholo ea likokoana-hloko, ho kenyelletsa le hlobo le algae.Ho eketsoa ha li-antifungal le antibacterial agents (tse kang biocides) ho thibela kholo ea likokoana-hloko le ho boloka ponahalo le nako e telele ea ho roala.
3.4.Moemeli oa ho thibela metsi:
Lisebelisoa tsa ho thibela metsi li bohlokoa bakeng sa lipente tsa ka ntle ho thibela ho kenella ha metsi, tse ka lebisang ho senyeha ha ts'ebetso le tahlehelo.Li-silicone, li-silane le metsoako ea fluorinated li atisa ho sebelisoa ho thibela metsi ho theha mokoallo oa hydrophobic le ho eketsa khanyetso ea ho roala ho senya metsi.
3.5.Sehlomathisi sa Impact resistance:
Bokaholimo bo ka senyeha habonolo ho tsoa mehloling e fapaneng, ho kenyeletsoa sefako kapa ho ama 'mele.Keketso ea li-influencer-resistant, joalo ka li-polymers tsa elastomeric kapa li-microspheres, li ka ntlafatsa bokhoni ba seaparo sa ho mamella khatello ea maikutlo le ho boloka thepa ea eona ea ts'ireletso.
Tšebelisano lipakeng tsa cellulose ethers le li-additives:
Motsoako oa li-cellulose ethers le li-additives ka lipente tse ka ntle hangata li baka phello ea synergistic e ntlafatsang tshebetso ka kakaretso.Sebopeho sa thixotropic sa cellulose ethers se tlatsana le thepa ea ho qhalakanya le ho tsitsisa ea li-additives tse itseng, ho ntlafatsa kopo le sebopeho sa filimi.
Mehlala le mehlala:
Karolo ena e fana ka mehlala ea 'nete ea lipente tse atlehileng tsa kantle tse kopanyang li-cellulose ethers le li-additives tse fapaneng.Liphuputso tsa liketsahalo li totobatsa liphephetso tse tobileng tse rarollotsoeng, lintlafatso tse fihletsoeng, le katleho e akaretsang ea moralo tlas'a maemo a fapaneng a tikoloho.
Mekhoa le mekhoa ea nakong e tlang:
Ha tlhoko ea liphahlo tsa kantle tse sebetsang hantle haholo e ntse e hola, indasteri e ntse e paka lipatlisiso tse tsoelang pele le nts'etsopele.Mekhoa ea nakong e tlang e ka kenyelletsa ho kopanngoa ha li-coatings tse bohlale, li-nanomaterials tse tsoetseng pele le li-additives tse tsitsitseng ho ntlafatsa ho tšoarella, botsoalle ba tikoloho le matla a matla.
ha re phethela:
Li-cellulose ethers le li-additives li phetha karolo ea bohlokoa ho ntlafatsa ts'ebetso ea liaparo tsa ka ntle.Kutloisiso e phethahetseng ea thepa ea bona le litšebelisano tsa bona ke ea bohlokoa bakeng sa baetsi ba lihlahisoa le bahlahisi ba batlang ho hlahisa liphahlo tse nang le nako e telele, e khomarelang, boemo ba leholimo le boleng ka kakaretso.Khatelo-pele e tsoelang pele ea thepa le theknoloji sebakeng sena e fana ka tšepo bakeng sa tsoelo-pele e tsoelang pele ea ho koahela ka ntle bakeng sa indasteri ea kaho.
