Iphepha lokuhluza ioli elinyangisiweyo

Ukunyanga isihluzo sephepha sinezinto zokungangeni manzi, iasidi, ubushushu obuphantsi, ubushushu obuphezulu, ukuxhathisa kwealkali. Isihluzo sephepha lokunyanga sisetyenziselwa ukuhluzwa komoya, umatshini wokucoca umda osebenzayo, ulungele umoya wento, uhlobo lusebenza kancinci, luphawulwa ngokumelana namanzi, ukuxhathisa kweasidi, ukumelana nobushushu obuphantsi, ukumelana nobushushu obuphezulu, ukuxhathisa kwealkali.

Iphepha lokucoca lisetyenziselwa ngokukodwa ukuvelisa zonke iintlobo zezihluzi zephepha kubenzi bokucoca. Isihluzo esenziwe ngephepha sisetyenziselwa ukususwa kothuli kunye nokungcola ngeendlela ezahlukeneyo zokuthatha i-injini, i-oyile kunye neendlela zamafutha ukukhusela kunye nokunciphisa ukuguga kwamacandelo e-injini kunye nokuqinisekisa ukwandiswa kobomi benkonzo ye-injini.

Isicelo

Isihluzi se-oyile yephepha eliqinileyo sibonisa ukungangeni kwamanzi, iasidi, ubushushu obuphantsi, ubushushu obuphezulu, ukuxhathisa kwealkali. Isihluzo sephepha lokunyanga sisetyenziselwa ukuhluzwa komoya, umatshini wokucoca umda osebenzayo, ulungele umoya wento, uhlobo lusebenza kancinci, luphawulwa ngokumelana namanzi, ukuxhathisa kweasidi, ukumelana nobushushu obuphantsi, ukumelana nobushushu obuphezulu, ukuxhathisa kwealkali.

1. Iphepha lokucoca lisetyenziselwa ngokukodwa ukuvelisa zonke iintlobo zezihluzi zephepha kubenzi bokucoca. Isihluzo esenziwe ngephepha sisetyenziselwa ukususwa kothuli kunye nokungcola ngeendlela ezahlukeneyo zokuthatha i-injini, i-oyile kunye neendlela zamafutha ukukhusela kunye nokunciphisa ukuguga kwamacandelo e-injini kunye nokuqinisekisa ukwandiswa kobomi benkonzo ye-injini.

2. Izizathu kunye neenzuzo zokunyanga iphepha lokucoca
Iphepha elishinyeneyo elenziwe ngezinto zendalo zezityalo zefiber eluhlaza alikwazi ukuhlangabezana neemfuno zemveliso kunye nokusetyenzwa kwesixhobo sokucoca kunye nokusetyenziswa kwephepha lokucoca ngokwalo ngenxa yokuqina kwayo okuncinci, iphepha lokucoca, amandla aphantsi, ukuthungwa okuthambileyo, ukufunxwa kakuhle kwamanzi. kunye nezinye izizathu. Ngoko ke, iphepha lokucoca kufuneka lifakwe (lifakwe) ekulungiseleleni i-resin enokuphucula amandla omzimba kwaye ayichaphazeli kakhulu ukunyanzeliswa komoya, oko kukuthi, unyango lokunyanga lwephepha lezibuko, ukwenzela ukuhlangabezana nokusebenza okukhethekileyo iphepha lokucoca. Unyango olunyangayo lwephepha laseHong Kong lusetyenziswa ikakhulu kwintlaka enyibilikayo yotywala kunye nentlaka enyibilikayo emanzini, kunye nentlaka enyibilikayo ngotywala inephenolic resin, i-trimerless resin njalo njalo.

I-Phenolic resin idla ngokusetyenziswa, inkampani yombhali isebenzisa umthi we-phenolic we-thermosetting ukuze ifake (i-coating) isiseko sephepha lesiseko sephepha, isihluzo sephepha esenziwe ngale ndlela sinamandla kwaye siqinile, sinokuchasana kweekhemikhali kunye nezinye iingenelo, ekuqiniseni kunye nefuthe lokumelana namanzi. kunokuba i-resin enyibilikayo yamanzi ayiphuli (i-coating) unyango
