Chenjezo Lofunika: Awa ndi mawu osungira zakale, osati malingaliro apano, kuunika kwachiwopsezo kapena malangizo owumitsa nkhuni mu petrolatum wotentha. Kutentha, akasinja, kutentha, mpweya wabwino, kukweza, zipangizo zamafuta, mpweya, chitetezo chamoto ndi kuphulika, thanzi la ogwira ntchito ndi chitetezo cha chilengedwe ziyenera kufufuzidwa motsatira malamulo omwe alipo komanso akatswiri ovomerezeka.
Lembali silopereka petrolatum, zowumitsa kapena mapangidwe a zomera zotere ndi Savo Kusić. Kupereka kwapano kumangoyang’ana mazenera, zitseko ndi mayankho ogwirizana.
Zolemba zakale ndi ndondomeko
M’mabizinesi opangira matabwa amakampani omanga, kuyanika matabwa ocheka kumagwiritsidwanso ntchito mu petrolatum. Petrolatum ndi zowonongeka zomwe zimapezeka panthawi yokonza mafuta a petroleum kuti azipaka mafuta.
Ndi chisakanizo cha parafini, ceresin ndi oyeretsedwa viscous mafuta. Pa kutentha20o petrolatum ili ndi mtundu wachikasu ngati udzu. Mphamvu yokoka yake yeniyeni ndi pafupifupi0.9, kutentha kosungunuka250o, kuchiritsa kutentha50o. Kugwiritsa ntchito petrolatum poyanika 1mmitengo ya coniferous kuyambira20ku25 kg. Mtengo wa kuyanika koteroko ndi wotsika kuposa mtengo wa kuyanika m’zipinda zowumitsa.

Zida zakale
Kupanga zowumitsa mafuta (Chith1) ndizosavuta. Amakhala ndi thanki yachitsulo yomwe imayikidwa mu dzenje la konkire ndipo amapangidwa ndi ubweya wa slag kuti azitha kutentha. Pansi pa thanki pali mapaipi otenthetsera petrolatum, momwe mpweya wa nthunzi kapena mpweya umalowa. Mitengo yocheka imayikidwa muzitsulo zapadera, zomwe zimatsitsidwa mu thanki ndi mafuta otentha pogwiritsa ntchito chogudubuza chamagetsi.
Kutentha kwakanthawi komanso nthawi yayitali
Kutalika kwa kuyanika kumatengera kutentha, komwe kwa zida zofewa zofewa zimatha kufikira i140o, ndi kwa olemera kwambiri110o. Malingana ndi deta, matabwa ocheka kuchokera ku coniferous wood ndi wandiweyani25 mmkuchokera ku chinyezi45%ku chinyezi15%umauma chifukwa3h ,ndi40-45 mm-kwa8h. Mabedi agawo100x100 mmiwo amawuma kwa22-24h, yomwe ili pafupifupi15-20nthawi mofulumira kuposa kuyanika m’zipinda za nthunzi.
Pambuyo kuyanika, zinthuzo ziyenera kusungidwa m’chipinda chozizira kapena m’nyumba yosungiramo katundu kwa masiku awiri kapena atatu, kenako zikhoza kukonzedwa pamakina.
Kufotokozera m’mbiri yamakhalidwe ndi malire
Kuyanika kwamitengo ya coniferous ndi coarsely porous ndikokwanira. Mitengo ya thundu ndi nkhuni zamitundu yayikulu yamitundu yayikulu ikawuma mu petrolatum imapereka zinyalala zambiri chifukwa chopanga ming’alu yamkati. Petrolatum amalowa mkati mwa matabwa, omwe amauma mpaka kuya2 mm; ndi izi, nkhuni zimakhala ndi antiseptic, koma kutumphuka kwa petrolatum, komwe kumapangidwa panthawiyi, kumapangitsa kuti zikhale zovuta kukonza nkhuni ndi makina. Kuphatikiza apo, pamitengo yowuma yochekedwa, kugawa kosagwirizana kwa chinyezi kumatha kuwonedwa kudutsa gawolo, lomwe, kutengera mtundu wa nkhuni, kuyambira6ku14%.
