I-Chlorinated Polyethylene ePhezulu (HCPE)
I-polyethylene ephezulu eneklorini (HCPE), eyimveliso eyoluliweyo ye-polyethylene eneklorini (CPE), luhlobo lweekhemikhali ezintle kunye nemathiriyeli yepolymer eyenziweyo esebenza ngokugqwesileyo.
I-polyethylene ephezulu ye-chlorine iveliswa yi-polyethylene ekhethekileyo ngokusebenzisa i-chlorination enzulu.
Umxholo we-chlorine weHCPE unokulawulwa ukusuka kwi-58% -75% ngokweemfuno zabathengi, kunye nokusebenza okuzinzileyo kweekhemikhali.
Inokunyibilika kwizinyibilikisi zendalo ezahlukahlukeneyo, i-hydrochloric ether, i-ketone kunye ne-esters, paritcualrly enkulu ukunyibilika kwi-methylbenzene kunye nesisombululo sexylene.
I-HCPE inozinzo oluphezulu lweekhemikhali ngokusekwe ekugcwaliseni kwayo ubume bemolekyuli kunye nezixa ezikhulu zeeathom zeklorini, eyona nto igqwesileyo yokwaleka kunye nefilimu yokwenza iresin kunye nentlaka yokuncamathelisa,
I-HCPE yenza i-coating yenze ifilimu ngokulula, ukunganyangeki kwe-oyile, ukunganyangeki kwe-ozone, i-anti ultraviolet, ukuxhathisa ukubola kweekhemikhali, ukuxhathisa kwe-asidi, ukuxhathisa kwe-alkali, kunye nesakhono esihle sokulwa ne-ultraviolet, akukho kusabela ngayo nayiphi na ityuwa ye-inorganic, i-retardant yomlilo, ukunganyameki kakuhle kwamanzi kunye nomphunga. , ukuxhathisa kwegesi yeklorini emanzi, i-CO2, i-SO2, i-H2S, ukuzinza okulungileyo kobushushu okuya kuphuka xa ubushushu bungaphezu kwe-130 ngelixa ukhulula i-HCL,
Inokugcinwa phantsi kobushushu obuqhelekileyo, inamandla ancamathelayo aphezulu kunye nomphezulu weemveliso zentsimbi kunye nesamente, kwaye isetyenziswa ngokubanzi kwipanit ekhethekileyo ye-anti corrosive kunye ne-adhesive.
Ukusetyenziswa kweHCPE
1.Ipeyinti ekhethekileyo yokunqanda ukugqwala: ipeyinti yaselwandle, ipeyinti yesikhongozelo, i-anti-corrosion primer, ipeyinti yokunqanda ukugqwala, ipeyinti enqanda ukugqwala, i-anti corrosive lacquer enamel, i-anit corrosive kunye nepeyinti yomhlwa, i-anti corrosion peyinti, ipeyinti enzima (ibhulorho, isakhiwo sentsimbi, umatshini wekhemikhali, umzi-mveliso wetyuwa, umatshini wokuloba), ukugquma kombhobho njl.
2.Ipeyinti engacimi umlilo, ipeyinti enqanda amadangatye, ukwambathisa umphandle womthi kunye nesakhiwo sentsimbi.
3.Ukwakha i-coating, i-coating yesakhiwo ehonjisiweyo,ipeyinti ekhonkrithi ngaphandle kwe-primer.
4.Ipeyinti yophawu lwendlela : ukupeyinta kwisikhululo seenqwelomoya, ipeyinti yokumakisha yendlela, ipeyinti ephawula indlela kunye nepeyinti ekhanyayo yendlela.
5.Ukuncamathelisa: ikakhulu isetyenziselwa ukudibanisa iimveliso ezahlukeneyo ze-pvc ezifana ne-PVC umbhobho wofakelo lwe-PVC, iprofayili ye-PVC.
6.Inokusetyenziswa njengezinto zokuqala ze-inki yokuprinta kunye ne-adhesives.
7.Isenokusetyenziswa njengesixhobo sokubuyiswa komlilo ephepheni nakwintsimi yefayibha, isilungisi esinganyangekiyo kubushushu kwindawo encamathelayo kwiimveliso zerabha (umxholo ophambili yi-neoprene), isilungisi kwi-inki yephepha kunye nefoyile ye-aluminium.
I-HCPE yeyona nto ibalaseleyo yokwenza ifilim yepeyinti ekhethekileyo ye-anticorrosive, enezibonelelo zokusetyenziswa kwexesha elide, yomile ngokukhawuleza, ayinamda kubushushu, icandelo elinye, elingenatyhefu, njl.

Ukhuseleko kunye nempilo
I-HCPE (i-High Chlorinated polyethylene) yimveliso yeekhemikhali ezicocekileyo ngaphandle kwe-caron tetrachloride eshiyekileyo kwaye ayinavumba, ayinayo ityhefu, ayinamlilo, izinzile kwaye ayinabungozi emzimbeni womntu.
Ukupakisha, ukugcinwa kunye nokuthutha
20+0.2kg/ibhegi,25+0.2kg/ibhegi,
Ibhegi yangaphandle: I-PP ibhegi enithiweyo.
Isingxobo sangaphakathi: Ifilimu ecekethekileyo yePE.
Le mveliso kufuneka igcinwe kwindawo eyomileyo nengena umoya ukunqanda ukukhanya kwelanga, imvula okanye ubushushu, kufuneka kwakhona ihanjiswe ngezikhongozeli ezicocekileyo, le mveliso luhlobo lwempahla engenabungozi.
