Kuphela P-4: Ukucaciswa, futhi Isicelo

Modern zokwakha emakethe ligcwele ukukhiqizwa upende, ukuba alulaze edinga kumakhemikhali awuketshezi akhethekile thinners. Ngo ukwakheka, zingabantu organic wezinto ezingaphili, futhi ngesilinganiso ukuhwamuka - okusheshayo, isebenziseka ngezindlela eziningi futhi kancane. Uhlobo ngalunye yakhelwe ukwenza imisebenzi ehlukene. Phakathi kwalezi ivelele ngokuba yokusebenza kwalo ngezindlela eziningi brand kuphela F-4. He is i material zibalulekile ekufezeni Umdwebo imisebenzi njengoba kusiza ukuthuthukisa solubility upende kanye varnishes.

Ukuqokwa kanye nendlela okwakheke ngayo impahla

Ifanele kuphela P-4 ngoba lo dilution imikhiqizo upende eyenziwe vinyl chloride copolymers, polyvinyl kampompi ukuxova umuthi wokugoma chloride, futhi epoxy inhlaka. Lusebenza izixazululo eziyinkimbinkimbi, njengoba izingxenye ezingaphezu kuka ezimbili kufakwe ngezithako zawo. Kuphela sakhiwa enjalo compounds oluyingozi organic ezifana butyl acetate - 12% acetone - 26% toluene - 62%.

Ngo womshini esebenzisa ubuchwepheshe yesimanje kanye nemishini, iqinisekisa a high. Kuphela P-4 ngenxa impahla yayo ngesivinini kakhulu inqubo kuhlangana. Ukusetshenziswa Its kwenza kube nokwenzeka ngesikhathi esifushane ukuthola upende iyunifomu isilungele ukusetshenziswa.

izici Kobuchwepheshe uketshezi

Ngesisekelo kuphela zangaphandle P-4 - umbala esobala kungekho nto enemibala emihle noma aphuzi futhi nephunga ethize ketshezi. It ingxenyenamba mass amanzi kuyinto 0.7%; inombolo acid ezingekho ngaphezu 0,07mg Koh / g; flashpoint - 7 ° C; inombolo coagulation - 24%; autoignition lokushisa - 550 ° C.

kuphela Universal P-4, izici okukuvumela ukusebenzisa kwayo i-varnishes eziningi enamels ethandwa kakhulu phakathi abathengi. Inhlanganisela amalungu yezingxenye ezintathu ngempumelelo inomthelela ukujiya yokuqedela of upende varnishes ukuze viscosity ukusebenza.

isicelo

Ukuze dilution ka varnishes nopende esetshenziselwa umhlobiso, kodwa futhi ngoba ukulungiselela ebusweni isicelo P-4 kuphela. Paints zisetshenziswa ebusweni ngokulinganayo ngakho akumele iqukathe izigaxa, okuyinto ku omiswe delaminate. Ukuze uwalethe ukungaguquguquki oyifunayo, uketshezi sengezwe enamels, kwenziwa, putty izingxenyana ezincane, kuyilapho ibangele kahle. Ukuhlanzwa evele kusuka amafutha nokungcola usebenze zidwedwe ubudala ofakwe isixazululo. Ayahwamuka, ifilimu Kumiswa eqina futhi iba enamathela lokuvikela ebusweni ngayo.

Ukungeza kuphela e upende P-4, ogama intengo ngayinye 1 ilitha ruble 90, ukunciphisa ukusetshenziswa yabo futhi bandise nekhono lokusingatha surface, endaweni enkulu kunaye. ukuxuba amazinga Kunconywa ngumkhiqizi ikhambi emaphaketheni. Kuphela P-4, ogama ukucaciswa kahle eliphezulu, efanelekayo dilution grey enamels futhi CHV-124 okhakhi. Futhi, le nto ingasetshenziswa diluting Izingxube ezifana:

• Ukwakheka OS 51 03 12 03;
• Koqweqwe lwawo "Evinal 28"; "Vinikolor"; EP 140 439; "Vinikor 62"; XB 518, 125, 714, 1120; "Evikor";
• primer XC 04, 062, 059, 077; "Vinikor 061"; EP 0263, 0103, 0508, 0259;
• varnishes brand XC 76 KhSL, XC 724, HV 784;
• putty EP 0020, 005 HV.

izinyathelo zokuvikeleka

Kuphela P-4 - iwuketshezi kokuba umphumela onamandla kuyacasula esikhumbeni, ulwelwesi lwamafinyila kwamehlo kanye ukuphefumula. Kuyinto anobuthi, oluvuthayo ngisho alufakwa. Kuphela P-4 oluyingozi kakhulu kanye 3 iphathelene ekilasini ingozi. Ukusebenza naye, kufanele ulandele abanye izinyathelo zokuphepha.

Ukuze siqhube umsebenzi usebenzisa le nto kufanele ababhemayo kokuba umoya omncane, kude amalangabi evulekile, ezingeni lokushisa +5 ... + 30 ° C kanye nomswakama isihlobo 85%. Lapho usebenzisa kuphela kwenqatshelwe ukubhema. Le into inhlekelele phezu contact nge oxidants ezifana acetic acid kanye nitric acid, i-hydrogen peroxide, futhi chloroform futhi bromoform.

Lokhu kwaziswa kuyinto anobuthi. Lapho-ke iyasha ngokushesha kakhulu engcolisa umoya ukuthi ungase udale umonakalo omkhulu impilo yabantu. Ukuvikelwa zokuphefumula kubalulekile ukusebenzisa ngomshini. Endabeni ka ukuxhumana izandla noma kwezinye izindawo, uketshezi kumele wageza off ngamanzi.

isitoreji

I kuphela R-4 - kuba inflammable futhi enobuthi, ngakho-ke kumele igcinwe ngokuphephile esitsheni evaliwe, kude heater, ukudla, izinto zikagesi, ezindaweni ezingafinyeleleki izingane, futhi ukugwema elangeni. Kuziwa emakethe izigubhu esakhiwe ngezinto amelana izingxenye zalo. Ikamelo lapho kuphela lilondolozwe, kufanele kube khona ingozi yomlilo. Impilo kusukela usuku ukwakhiwa kuyinto ezingu-12.
