Nazinkinga 646: iinkcukacha, GOST, ukubunjwa

Nazinkinga 646 nazinkinga esebenzayo jikelele, yenzelwe ukuba isetyenziswe xa usebenza ipeyinti ezahlukeneyo. Ngenxa it ukutyabeka emva ukhanye ezongezelelweyo yokomisa zuza. Kweli nqaku uza kufunda:

- nto leyo kuphela 646;

- ezizodwa zobugcisa;

- Standard, iimfuno apho siyafana.

iimpawu ngokubanzi inyityilikiswayo

ibanga nazinkinga 646 - ulwelo ezingenambala ngaphaya (kwezinye iimeko unokuba ithinti tyheli), lubonakala, ivumba elithile. Ukuxinana nazinkinga yi 0,87 grams ngamnye cubic metres. 'Yabona, oko akuthethi ngumkhenkce kwaye akukho ukuzuza viscosity. It avuse ngokuzenzekelayo kubushushu degrees 403 nezilonda apha degrees 59.

Yenziwe ngokungqinelana na neemfuno GOST 18188-172. Isinyibilikisi kufuneka sisincoko efanayo. Kufuneka ukuba babonwe turbidity kunye delamination. Kwakhona akuvumelekanga ubukho amasuntswana abanqunyanyisiweyo kulwelo.

Eziveliswa zokubopha kwimizi kwizikhongozelo iplastiki neeglasi (iibhotile) ngobukhulu ezahlukeneyo.

646 Hluza iinkcukacha, isakhiwo

It is a ambaxa compounds organic izinto. Isinyibilikisi 646, iimpawu zazo ayangqinelana GOST 18188-72, iquka izithako zilandelayo:

• toluene - 50%;
• butanol - 15%;
• butyl acetate - 10%;
• ethyl spirt- 10%;
• acetone - 7%;
• ethylcellosolve - 8%.

Ngenxa lokuqamba yayo, kucingwa ukuba izinto exela kakhulu esebenzayo.

Nazinkinga 646 iinkcukacha zezi zilandelayo:

• eyazisa hexa of ethyl kaEtere kuluhlu ukususela-8 ukuya kwi-15;
• inombolo Coagulation elingana ubuncinane 35%;
• inani acid elingekho ngaphezulu kwe-0,06 mg Koh / g;
• inxalenye lwamanzi (Fischer) angekho ngaphezulu kwe-2%;
• ngokuxuba inyathelo - emva omiswe akukho waphawula ubukho mhlophe kunye umboniso nitroenamels lubonakala kumphezulu ogudileyo ngaphandle phambi amabala.

isicelo phi?

Nazinkinga 646 nokubalulwa nokuvumela ukusetyenziswa ukusebenza ezahlukeneyo Iipeyinti, kuquka nitrocellulose, melaninoamidnymi, glyptal, acrylic, epoxy. Oku kusetyenziswa nokuba isongezo ekuvelisweni kwezi zinto okanye ukuxutywa yabo ukuyondelelana ezinqwenelekayo ngaphambi kokuba uyisebenzise. Kwakhona, lo reagent yongezwe lokufaka kunye primer ngenxa workability kangangoko, evumela ogqibeleleyo ilungelelanise komhlaba.

Kwezinye iimeko, isinyibilikisi yi R-646, nto leyo kunxibelelana iinkcukacha BHALA, isetyenziswa njenge material for iindawo ezahlukeneyo bamafutha okanye izixhobo ukuhlamba (ukwandisa inkqubo ethile).

Ziziphi iingenelo wesinyibilikisi ezahlukeneyo 646?

Phakathi iingenelo eziyintloko uphawu 646 sijike zezi zilandelayo:

• Ukukwazi Lubonakala;
• amandla nazinkinga phezulu kakhulu;
• unika Ipeyinti isilungiseleli seglosi olongezelelweyo;
• kulula ukuyisebenzisa;
• It abuphumi kwimeko amanxeba zoqhagamshelwano phezu kobuso eluswini;
• It aluyiyo amabala kutyetyiswa kwi imiphezulu baphathwa;
• umphunga, engashiyanga ivumba.

umthamo

Isinyibilikisi idityaniswe ipeyinti okanye ivanishi iziqwenga ezincinane lexinene ezifunwayo kunye viscosity. Ngoko umxube owodwa kufuneka rhoqo ndixoxa namntu. Ekubeni isinyibilikisi has a umsebenzi omkhulu, ngoxa esebenza nayo kufuneka silumke ngakumbi ukuba ukuphazamisa umaleko ukutyabeka asezantsi.

amanyathelo okhuseleko xa usebenza kuphela

Kufuneka wenziwe kumagumbi kunye umoya okulungileyo, ngenxa yokuba into yityhefu (ihlelwa wesithathu udidi ingozi). Ukongeza, xa besebenza kunye amanqaku kwisinyibilkisi 646 ukuba kusetyenziswa ezifana PPE njenge baphefumla neeglavu. Kucetyiswa ukuba basebenzise iindondo zokhuseleko.

Ukuba umthengisi waba kwingingqi eluswini, kufuneka ziphathwe ngamanzi (ashushu) kunye ngesepha. Kwimeko lokudibana kunye inwebu kwiinwebu iliso emva kokuhlamba kufuneka udibane nogqirha.

Sisazi ukuba sijike kuyinto material olunokutsha, kuyimfuneko ukuba uliphathe ngenyameko yaye naphantsi kwazo naziphi na iimeko musa ukuvumela ukuvula amadangatye, iintlantsi kunye nokutshaya kufutshane matanki kunye reagent.

Indlela ukugcina?

Isinyibilikisi elondolozwe ku ngesitya sivalisisekile ngalo lonke ixesha. Ngaphezu koko, ne izikhongozeli reagent kufuneka bakhuselwe ukufuma, kwelanga ngqo kunye nobushushu. Awukwazi ushiye naziphi na izixhobo zokufudumeza kufutshane izikhongozelo zesinyibilikisi.

Ithuba iwaranti zokugcina (njengoko abavelisi ulwazi) ukusuka kumhla wokwenziwa ziinyanga ezili-12, nto leyo eyenza amashishini ukuba bathenge le mveliso kukuninzi.

Amaxabiso lobushushu apho isinyibilikisi egcinwe, ke uluhlu ukusuka thabatha 40 dibanisa 40 amaqo.
