    LITŠOANTŠISO KHETHO

    Phenol-formaldehyde resin e lokiselitsoe ka tsela e latelang:
    C6H5OH+H2C=O —> [-C6H2(OH)CH2-]n
    Li-resin tsa Mokhahlelo o le Mong. Karo-karolelano ea formaldehyde ho phenol e phahame ka ho lekaneng ho lumella mokhoa oa thermosetting hore o etsahale ntle le ho eketsoa ha mehloli e meng ea li-cross-link.
    Li-Resins tse Mehato tse peli. Karo-karolelano ea formaldehyde ho phenol e tlase ho lekana ho thibela karabelo ea thermosetting ho etsahala nakong ea ho etsoa ha resin. Mothating ona resin e bitsoa novolac resin. Ka mor'a moo, hexamethylenetetramine e kenngoa ka har'a thepa ho sebetsa e le mohloli oa li-cross-link tsa lik'hemik'hale nakong ea ts'ebetso ea ho bōpa (le ho fetolela ho thermoset kapa boemo bo phekotsoeng).

    KOPO SEBAKA

    Li-phenolic resin li sebelisoa bakeng sa likarolo tse theko e tlase tse hlokang thepa e ntle ea ho sireletsa motlakase, ho hanyetsa mocheso kapa ho hanyetsa lik'hemik'hale. Kakaretso ea nako ea bophelo ba resin ena e ka ba khoeli e le 'ngoe ho 21.1°C. Sena se ka atolosoa ka ho se boloka ka sehatsetsing ho 1.6 ho isa ho 10°C. Ho feto-fetoha ha motsoako (ho ea ka botenya ba samente) le ho phahamisa mocheso oa pholiso ho 93 ° C ho tla fetola nako ea phekolo ho tloha ho lihora tse 8 ho isa ho tse khutšoane joalo ka 15 min.
    Ho honyela ho hong ho etsahala ha ho phethoa (0.012 ho isa ho 0.6 mm/mm), ho ipapisitse le bongata ba setlatsi, palo ea lintho tse thusang, le sekhahla sa pheko. Mehato e potlakileng ea kalafo e hlahisa sekhahla se phahameng sa shrinkage. Kaha potoloho ea pheko e ka potlakisa, li-phenolic li sebelisoa ts'ebetsong ea nako e khuts'oane.
    Likarolo tsa "cast phenolic" li tlosoa habonolo hlobong haeba ho sebelisoa lisebelisoa tsa karohano tse khothaletsoang ke morekisi. Posteuring e ntlafatsa thepa ea motheo ea ho lahla ho felile.

    MOKHOA OA HO REKA HO RONA

    Chemwin e ka fana ka mefuta e mengata ea li-hydrocarbon tse ngata le li-solvents tsa lik'hemik'hale bakeng sa bareki ba indasteri.Pele ho moo, ka kopo bala lintlha tse latelang mabapi le ho etsa khoebo le rona: 

    1. Tshireletso

    Tšireletseho ke eona ntho e tlang pele bophelong ba rona. Ntle le ho fa bareki tlhahisoleseling mabapi le ts'ebeliso e sireletsehileng le e baballang tikoloho ea lihlahisoa tsa rona, re boetse re ikemiselitse ho netefatsa hore likotsi tsa polokeho ea basebetsi le borakonteraka li fokotsoa ho ba bonyane bo utloahalang le bo ka khonehang. Ka hona, re hloka hore moreki a etse bonnete ba hore litekanyetso tse nepahetseng tsa ho laolla le ho boloka polokeho li fihlelleha pele ho tlisoa ha rona (ka kopo sheba sehlomathiso sa HSSE ho latela maemo le maemo a kakaretso a thekiso a ka tlase). Litsebi tsa rona tsa HSSE li ka fana ka tataiso mabapi le litekanyetso tsena.

    2. Mokhoa oa ho fana

    Bareki ba ka odara le ho fana ka lihlahisoa ho tsoa ho chemwin, kapa ba ka fumana lihlahisoa ho tsoa femeng ea rona ea tlhahiso. Mekhoa e teng ea lipalangoang e kenyelletsa lipalangoang tsa literaka, terene kapa mefuta e mengata (maemo a arohaneng a sebetsa).

    Tabeng ea litlhoko tsa bareki, re ka hlakisa litlhoko tsa likepe kapa litanka mme ra sebelisa litekanyetso tse khethehileng tsa polokeho / tlhahlobo le litlhoko.

    3. Palo e fokolang ea taelo

    Haeba u reka lihlahisoa sebakeng sa rona sa marang-rang, palo e tlase ea odara ke lithane tse 30.

    4.Tefo

    Mokhoa o tloaelehileng oa ho lefa ke ho fokotsa ka kotloloho matsatsing a 30 ho tsoa ho invoice.

    5. Litokomane tsa thomello

    Litokomane tse latelang li fanoe ka thomello ka 'ngoe:

    · Bill of Lading, CMR Waybill kapa tokomane e 'ngoe e amehang ea lipalangoang

    · Setifikeiti sa Tlhahlobo kapa Tumellano (haeba ho hlokahala)

    · Litokomane tse amanang le HSSE tumellanong le melaoana

    · Litokomane tsa meetlo ho latela melaoana (haeba ho hlokahala)
