I-P4 iinkcukacha ezinganyibiliki kakhulu, isakhiwo

Kuba ngempumelelo imisebenzi ukupeyinta nawo okunye ezibalulekileyo ezifana izinyibilikisi, sebenzisa ogama kuyimfuneko ukulungisa umphezulu nokugqithisa ukuyondelelana ezinqwenelekayo izinto yepeyinti. Kweli nqaku siza kuxubusha P4 inyityilikiswayo, leyo yenye adume kakuhle yaziwa emarikeni izinto ezifanayo.

iimpawu ngokubanzi

P4 sijike - an isinyibilikisi eziphilayo leyo ulwelo ezingenambala ecacileyo (kwezinye iimeko unokuba ithinti bulubhelu) ngaphandle amasuntswana ebonakalayo lunqunyanyisiwe. Oku lubonakala ivumba ethile kunye hexa eliphezulu. Ixabiso avareji lexinene xa kuthelekiswa ukwimo yi-0.85 g cc nganye. cm. autoignites kubushushu degrees 550. Yavelisa ngokwemigangatho ebekwe GOST 7827-74. Iveliswe kwisikhongozeli mveliso - yeplastiki kunye zeglasi (iibhotile) ngobukhulu ezahlukeneyo.

P4 nazinkinga: Ukubunjwa

P4 - umxube izinyibilikisi ezintathu organic, leyo ngokudibeneyo ukufumana impumelelo engakumbi. Oku kuquka izinto ezilandelayo:

• Toluene - 62%;

• acetone - 26%;

• butyl acetate - 12%.

Ngenxa zithako sijike eyaneleyo iipropati yabathengi elungileyo kunye nokuchithwa ukusebenza eliphezulu ivanishi kwakunye ipeyinti. izithako ezifana butyl acetate, kwandisa bhanya isilungiseleli seglosi isicelo Ipeyinti kwaye uthintele mhlophe kunye mhlophe.

I-technical iparameters ephambili isinyibilikisi

I-P4 nazinkinga (GOST 7827-74) ukuba ezi mpawu zilandelayo:

• ixabiso Isalathisi hexa kwe ethyl kaEtere kuluhlu ukususela-5 ukuya kweli-15;

• Inombolo coagulation ayikho ngaphantsi kwe-24%;

• umyinge wamanzi (ngokomthamo) ayikho ngaphezu kwe-0.7%;

• iasidi inani hayi ngaphezulu kwe 0,07 mg Koh / g.

Ifumaneka njengoko grade kuphela P-4A. Le reagent kunye P4 nesinyibilikisi - analogs kwemigaqo. Noko ke, zahluke ngobunto ukwakheka, ukususela, ngokungqinelana neemfuno ezimiselweyo GOST, kwi-P-4A ayibandakanyi butyl acetate. Omnye umahluko kukuba ezi mpawu ukuba brand ezinganyibiliki F-4Kaloku, ngokungafaniyo P4 iyanyibilika wayesebenzisa CHV-124 (zokuzikhusela grey).

Enanikade isinyibilikisi wasebenzisa P4?

Le reagent esetyenziselwa ukufuya iipeyinti uchwetheze PSC PSC LN kunye LS, isiseko imveliso apho ikhlorini Polyvinyl nentlaka chloride, nentlaka epoxy, IVinyl copolymers chloride kunye nezinye izinto bhanya-bokwakha.

Umthamo - ukuba yaze yangxenga ifuthe lomanyano indlela ipeyinti P4 inyityilikiswayo?

P4 sijike idityaniswa ezibonakalayo ethile (ivanishi okanye ipeyinti) e iinxalenye ezincinane de ukuvumelana oyifunayo. paint Amazing (lacquer) ifuna sibanga rhoqo.

Emva kokuba isicelo ukutyabeka uzilungiselele osha nazinkinga kunye bhanya-yakheka izinto ziyahlala, ajike abe ukutyabeka olukhuselayo. Kubalulekile xa usebenza nge kwisinyibilkisi ukuthintela ukungena kwamanzi abe yinxalenye acetone inokuba lula mix nayo, yaye oku kuya kukhokelela uhlaba lombala okanye mhlophe kophawu ecacileyo.

amanyathelo okhuseleko xa usebenza nge P4 ezinganyibiliki

Kufuneka kukhunjulwe ukuba impahla fanele ukuya toxicant kwaye abe negalelo elibi emzimbeni womntu, onikezelwa yi inhalation, kwaye ingena kulusu. Ngu elide exposure kunokwenzeka nefuthe elibi isinyibilikisi kwi ukuba umongo kunye negazi. Kwimeko qha elide kunye nesikhumba abunjwe dermatitis.

Ukuqwalasela zonke ngasentla, kunye P4 inyityilikiswayo kufuneka kwenziwa kwizakhiwo, ngokubonelela umoya olungileyo. Kubalulekile kwakhona ukuba asebenzise izixhobo zokhuseleko ukuthintela utyhileko izinto eziyingozi kwi inkqubo yokuphefumla, amehlo kunye nesikhumba kwezandla (baphefumla, iiglavu, izibuko).

P4, kwakunye neqela kwezinye izinyibilikisi, ebonakala iqondo eliphezulu ingozi yomlilo. Lo mxube ke ngokukhawuleza, kwaye, ngaphezu koko, ukuba Uyadubula. Couples ezakha lunezinto isakhiwo ukuqokelela isinyibilikisi nazo kuqhume. Ngoko ke, kuyimfuneko ukuba sijike liyithobele na iimfuno zokhuseleko ngomlilo.
