1. Ukubuka konke kwe-methyl hydroxyethyyl celtulose (Mhec)
I-methyl hydroxyethyl celtulose (Mhec) yi-ether engekho i-ether ether etholwe ukuguqulwa kwe-methylation ngesisekelo se-hydroxyethyl cellulose. Ngenxa yesakhiwo sayo esiyingqayizivele se-molecular, i-MHEC ine-soubity enhle, ukuqina, ukunamathela, umsebenzi owenziwe ngefilimu nomsebenzi, futhi kusetshenziswe kabanzi kuzimbali, izinsiza zokwakha kanye nezinye izinkambu.

I-Peant Strippers ngamalungiselelo amakhemikhali asetshenziselwa ukususa izimbotshana ezingaphezulu njengezinsimbi, izinkuni namapulasitiki. Izingqinamba zopende zendabuko zincike kakhulu ezinhlelweni ze-solvent ezinzima, njengeDichloromethane neToluene. Yize lawa makhemikhali esebenza kahle, anezinkinga ezinjengokuqina okuphezulu, ubuthi kanye nobungozi bezemvelo. Ngemithethonqubo eqinile yezemvelo kanye nokwenza ngcono kwezidingo zomsebenzi wokusebenza, ama-stripers asuselwa kupende anobuthi anobuthi aqala kakhulu abe nzima kakhulu emakethe.
I-3. Indlela yokusebenza kwe-MHEC ku-Paint Hards
Ku-Paint Hards, uMhec udlala indima ebalulekile njengomugqa omkhulu kanye ne-rheology modifier:
Umphumela wokuqina:
I-MHEC inomthelela omuhle kakhulu ezinhlelweni ezisuselwa emanzini. Ngokushintsha ukubonwa kwe-stripper yopende, i-mhec ingenza umxhwele ngopende anamathele ezindaweni eziqonde mpo noma ezithambekele ngaphandle kokugcwala. Le mpahla ibaluleke kakhulu ngesikhathi sokusebenza kwezithuthukisi zopende ngoba ivumela ukuthi i-stripper yokupenda ihlale endaweni eqondiwe isikhathi eside, ngaleyo ndlela yenza ngcono umphumela wokudonsa ngentambo.
Qinisa uhlelo lokumiswa:
Izicucu zopende zivame ukuqukethe izithako ezahlukahlukene ezisebenzayo, ezingase zihlukanise noma zixazulule ngesikhathi sokugcina. Ngokwenza ngcono ukwakheka kwesixazululo, i-MHEC ingavimba ngempumelelo ukuqunjelwa kwezinhlayiya eziqinile, gcina ukusatshalaliswa komfaniswano kwezithako, futhi kuqinisekiswe ukusebenza okuzinzile kwe-stripper yopende.
Lungisa izakhiwo ze-Rheological:
Ukusetshenziswa kwe-peint stripper kudinga ukuthi inezakhiwo ezinhle zesimbozo, okungukuthi, kungageleza kahle lapho kusetshenziswa amandla angaphandle, kepha angakhula ngokushesha lapho eqinile. Ukwakheka kwe-molecar chain yesakhiwo se-MHEC kukunikeza kahle izakhiwo ezinciphayo ezinciphile, okungukuthi, ngamanani aphezulu we-shear, ukubonakala kwesixazululo kuzokwehla, okwenza ukuthi i-stripper yepende ibe lula ukuyisebenzisa; Ngenkathi usezingeni eliphansi le-shear noma esimweni se-static, i-vispusity yesixazululo iphakeme, esiza ngokwezinto ezibonakalayo ifomu umfaniswano wokuhlobana.
Ukugqugquzela ukwakheka kwefilimu:
Ngesikhathi sokudonsa ngempumelelo inqubo, iMhec ingasiza i-Pint Stripper yakha ifilimu efanayo endaweni eqondiwe. Le filimu ayikwazi ukwandisa isikhathi sesenzo sezithako ezisebenzayo, kepha futhi ithuthukisa amandla okumboza we-pient stripper ngezinga elithile, ukuze ikwazi ukungena ngempumelelo kuzo zonke izingxenye zenhlanganisela.
4. Isebenzisa kanjani i-MHEC ku-Peant Strippers
Ukulungiselela ikhambi elinamanzi:
Ngokuvamile i-MHEC ikhona ngefomu le-powder futhi idinga ukulungiswa kwisisombululo esinamanzi ngaphambi kokusebenzisa. Umkhuba ojwayelekile ukungeza kancane kancane i-MHEC emanzini ashukumisayo ukugwema ukuhlangana. Kumele kuqashelwe ukuthi i-solubility ye-MHEC izothinteka ekushiseni kwamanzi nenani le-PH. Izinga lokushisa lamanzi aphezulu (50-60 ℃) lingasheshisa inqubo yokuchithwa kwe-MHEC, kepha izinga lokushisa eliphakeme kakhulu lizothinta ukusebenza kwalo kwe-viscosity.
Kuxutshwe ama-peint strippers:
Lapho ulungiselela izicucu zokupenda, ikhambi lamanzi le-MHEC livame ukungezwa kancane kancane ku-Pint Stripper Base ketshezi ngaphansi komoya. Ukuze uqinisekise ukusakazwa okufanayo, ijubane lokungezwa le-MHEC akufanele lisheshe kakhulu, futhi ukuvusa kufanele kuqhubeke kuze kutholakale isixazululo somfaniswano. Le nqubo idinga ukulawula ijubane lokuvuselela ukunqanda ukwakheka kwama-bubble.
Ukulungiswa kwefomula:
Inani le-MHC ku-Paint Strippers livame ukulungiswa ngokuya ngefomula ethile kanye nokwenza okuqondiwe kwe-Peant Strippers. Inani elingezelelwe elijwayelekile liphakathi kuka-0,1% -1%. Umphumela wokuqina oqinile ungadala ukuhlanganiswa okungalingani noma ukubonwa ngokweqile, ngenkathi umthamo olwanele kungenzeka ungakufeli ukuhlakanipha okuhle nezimbobo zesimbozo, ngakho-ke kuyadingeka ukuze uthole ukusetshenziswa kwayo ngokusebenzisa izivivinyo.
I-5
Ukuvikelwa Nezemvelo:
Uma kuqhathaniswa nabakhudlwana bendabuko, i-MHEC i-ether engekho emthethweni, ayinazo izinto ezinobuthi futhi eziyingozi, iphephe kakhulu emzimbeni womuntu kanye nemvelo, futhi ihambisana nokuqondiswa kwe-Chemistry yanamuhla.
Ukuqina okuhle: I-MHEC inokuqina okuhle kwamakhemikhali ngobubanzi be-PH (PH 2-12), kungagcina umphumela ozinzile oqinile ezinhlelweni ezahlukahlukene ze-stripper, futhi aziphazanyiswa kalula ezinye izakhi ohlelweni.
Ukuvumelana okuhle: Ngenxa yemvelo engeyona eye-ionic ye-MHEC, ihambisana kahle nezithako ezisebenzayo kakhulu, ngeke ihlanganyele noma ibangele ukungazinzi kahle kohlelo, futhi ilungele izinhlobo ezahlukene zokwenziwa kwepende.
Umphumela wokuqina osebenzayo: I-Mhec inganikeza umphumela obalulekile wokuqina, ngaleyo ndlela kunciphise inani labanye abakhulu ku-stripper yopende, yenza lula ifomula kanye nokunciphisa izindleko.
I-methyl hydroxyyethyl cellulose (Mhec) isetshenziswe kabanzi ku-Peast Pintpers yanamuhla ngenxa yokuqina kwayo okuhle, ukuqina kanye nokuhambisana. Ngokusebenzisa i-formula design enengqondo futhi usebenzise, i-MHEC ingathuthukisa kakhulu ukusebenza kwezithuthukisi zopende, ibenze babonise ukusebenza kahle okuphezulu nokuvikelwa kwemvelo ezinhlelweni ezisebenzayo. Ngokuzayo, ukuthuthukiswa okuqhubekayo kobuchwepheshe be-peint stripper kanye nokwenza ngcono okwengeziwe kwezidingo zokuvikelwa kwemvelo, amathemba wesicelo se-MHEC ku-Paint Strevers azobanzi.
