O mea fa'asalalau ma mea fa'alu'u e masani ona fa'aogaina fa'aopoopo i le fa'atusaina o lanu palasitika.Afai e faʻaopoopo nei mea faʻaopoopo i mea mataʻutia o le oloa, e manaʻomia ona faʻaopoopo i le resin raw material i le tutusa tutusa i le faʻamaonia o le lanu, ina ia aloese mai le eseesega o lanu i le gaosiga mulimuli ane.
O ituaiga o faʻasalalau o: polyureas gaʻo gaʻo, base stearate, polyurethane, fasimoli oligomeric, ma isi. O faʻasalalauga e masani ona faʻaaogaina i totonu o pisinisi o lubricants.Lubricants o loʻo i ai mea faʻasalalau lelei, ma e mafai foi ona faʻaleleia atili le suavai ma faʻasaʻo mea faʻasaʻo o palasiti i le taimi o le faʻaogaina.
Lubricants ua vaevaeina i totonu lubricants ma fafo lubricants.O lubricants i totonu o loʻo i ai se fesoʻotaʻiga faʻatasi ma resins, lea e mafai ona faʻaitiitia ai le felagolagomaʻi i le va o filifili mole mole resin, faʻaitiitia le viscosity liusuavai, ma faʻaleleia le suavai.O le fesoʻotaʻiga i le va o le lubricant fafo ma le resin, e pipii i luga o le resini uʻamea e fausia ai se lubricating molecular layer, ma faʻaitiitia ai le feteʻenaʻiga i le va o le resini ma meafaigaluega gaosi.Lubricants e masani ona vaevaeina i vaega nei e tusa ai ma lo latou fausaga faʻainisinia:
(1)) Vasega mu e pei o le paraffin, polyethylene wax, polypropylene wax, micronized wax, ma isi.
(2) Ga'o ga'o e pei o le stearic acid ma le base stearic acid.
(3) Fatty acid amides, esters e pei o le vinyl bis-stearamide, butyl stearate, oleic acid amide, ma isi. E masani ona faʻaaogaina mo le faʻasalalauina, lea e faʻaaogaina ai le bis-stearamide mo mea faʻamaʻi uma ma palasitika thermosetting, ma e iai sona aafiaga lubricating. .
(4) O fasimoli u'amea e pei o le stearic acid, zinc stearate, calcium stearate, pot stearate, magnesium stearate, lead stearate, ma isi mea uma e iai uma le faʻamautuina o le vevela ma le lubricating aafiaga.
(5) Lubricants o loʻo iai sona sao i le faʻasaʻoina o le limu, e pei o le polydimethylsiloxane (methyl silicone oil), polymethylphenylsiloxane (phenylmethyl silicone oil), polydiethylsiloxane (ethyl silicone oil) ma isi.
I le faʻagasologa o tui, pe a faʻaaogaina le lanu mago, o vailaʻau togafitiga e pei o le suauʻu minerale paʻepaʻe ma le suauʻu faʻasalalau e masani ona faʻaopoopoina i le taimi o faʻafefiloi e fai ai le sao o le adsorption, lubrication, diffusion ma le faʻasaʻoina o le limu.Pe a valivali, e tatau fo'i ona fa'aopoopo mea mata'utia i le fa'asoa fa'asoa.Muamua faʻaopoopo le vailaʻau togafitiga luga ma faʻasalalau tutusa, ona faʻaopopo lea o le toner ma faʻasalalau tutusa.
Pe a filifilia, e tatau ona fuafua le maualuga o le vevela o le dispersant e tusa ai ma le vevela o le palasitika o mea mata.Mai le vaaiga o le tau, i le mataupu faavae, o le dispersant e mafai ona faʻaaogaina i le vevela ma le maualalo e le tatau ona filifilia mo le maualuga o le vevela.Ole dispersant vevela maualuga e manaʻomia ona faʻasaʻo ile luga ole 250℃.
