Petroleum Jelly

Petroleum jelly isemi-mvura musanganiswa wealkyl hydrocarbons kana saturated hydrocarbons, inonziwo petrolatum, inogadzirwa nefractional distillation yepetroleum. Mamiriro ayo ari pakati pekusimba uye mvura pane tembiricha yekamuri, uye ine mavara matatu ebrown, yero uye chena nekuda kwezvinangwa zvakasiyana.

Natural petroleum jelly inotorwa kubva mupetroleum residue concentrate senge alkyl hydrocarbon heavy oil. Artificial petroleum jelly inotorwa kubva musanganiswa wemafuta emamineral akakora newakisi yepasi yakachena kana parafini negirisi yeparafini. Petroleum jelly ine mineral oil inonhuwira, kwete kunhuhwirira kweparafini. Inogona kushandiswa seyakabikwa yemishonga uye zvizorwa, uye inogona zvakare kushandiswa kugadzira muchina lubrication.

Kazhinji kazhinji, magirazi plugs mumaburets akaputirwa neatete layer yevaseline kuti awedzere kumonyoroka kwekuzora uye kuvhara mapeji. Kupinza chubhu yegirazi mugomba rerabha plug, isa petroleum jelly kuti uwedzere mafuta uye kuti chubhu ive nyore kuisa.

Pamusoro pezviri pamusoro, zvakapfava kuiswa kune kamera lens inogona kugadzira yakapfava yekutarisa hazy maitiro.

Tine mafekitori akawanda emhando yepamusoro nekubatana kwakadzama, ayo anogona kukupa zvigadzirwa zvemhando yepamusoro nemitengo yemakwikwi. Uye isu tinogonawo kupa zvidzikiso pakutenga kwakawanda. Uye isu tinobatirana nemakambani mazhinji ehunyanzvi ekutakura zvinhu, anogona kuendesa zvigadzirwa zvakachengeteka uye zvakanaka kumaoko ako. Nguva yekutumira inenge 3-20 mazuva mushure mekusimbiswa kwekubhadhara.
