Ukukhetha ngokuchanekileyo izongezo yinto ebalulekileyo ekuphuculeni iimpawu zendalo zezinto ezidityanisiweyo zomthi-plastiki (ii-WPC) kunye nokuphucula iimpawu zokucubungula. Iingxaki zokugoba, ukuqhekeka, kunye nokufaka idayi ngamanye amaxesha zivela kumphezulu wezinto, kwaye kulapho izongezo zinokunceda khona. Kumgca wokukhupha ii-WPC, izongezo ziyafuneka ukuze kufunyanwe isantya esifanelekileyo sokukhupha kunye nomphezulu ogudileyo ukuze kuthintelwe ukuqhekeka komphetho.
Phakathi kwezongezo ezahlukeneyo ezikhethiweyo, izinto zokuthambisa, izinto ezidibanisa izinto ezinqamlezayo, ii-antioxidants, izinto eziqinisa ukukhanya, kunye nee-anti-mold/anti-bacterial agents zinefuthe elikhulu kumgangatho wee-composites zomthi-plastiki. Ngokuphathelele izongezo ezikhethekileyo zee-composites zomthi-plastiki, ii-resin ezahlukeneyo ze-matrix kufuneka zenze izongezo ezikhethekileyo ukuze zihlangabezane neemfuno zokusebenza kwemveliso edibeneyo okanye ukusebenza kokucubungula, nangona kunjalo, kukho uluhlu olubanzi lwezongezo zee-composites zomthi-plastiki, kwaye ukukhethwa kwezongezo ezifanelekileyo kubalulekile ekuvelisweni kwee-composites zomthi-plastiki.
Indima yezongezo kwii-Wood-Plastic CompositesIintlobo kunye neenzuzo
Iarhente yokudibanisa
Ii-Crosslinking agents zidibanisa imicu yomthi kunye ne-matrix resin kunye, ziphucula amandla okuguquguquka kunye nokuqina kwezinto ezidityanisiweyo, kunye nokuphucula imodulus yokumelana nokuqhekeka kunye nemodulus yokuguquguquka. Ii-Crosslinking agents zikwaphucula uzinzo olulinganayo lwezinto, amandla okubetha, iipropati zokusasazeka kokukhanya, kunye nokunciphisa ukuqhekeka, okubaluleke kakhulu kwiimveliso ezinje ngee-balustrades, ii-stair railings, kunye nee-guardrails. Kwii-composites zomthi weplastiki ezisetyenziswa kwizixhobo zokuhombisa, indima ephambili ye-crosslinking agent kukunciphisa ukufunxwa kwamanzi kwezinto, okunokuthintela ukwenzeka kokuqhekeka koxinzelelo okubangelwa kukwanda kwemicu yomthi ngenxa yokufunxwa kwamanzi.
I-Antioxidant
Kwimveliso yomthi weplastiki, ukhetho oluphambili lwe-antioxidant yendabuko yi-BHT kunye ne-1010 iindidi ezimbini. Ixabiso le-BHT liphantsi kancinci, isiphumo se-oxidation esinganyangekiyo ubushushu kamva silungile, kodwa i-BHT ngokwayo emva kokuba idityanisiwe, iya kwenza i-DTNP, isakhiwo ngokwaso sinombala otyheli, kwimveliso yamabala anemibala, ngoko ke ukusetyenziswa kwayo akuxhaphakanga. I-1010 ayipheleli nje kwiimveliso zomthi weplastiki kodwa nakwishishini lonke le-polymer ineentlobo ngeentlobo zezicelo kwaye ikwayi-antioxidant ephambili enkulu nesetyenziswa kakhulu kwihlabathi.
Iiarhente ezilwa nokungunda/ezilwa neentsholongwane
Okwangoku, ii-arhente zeplastiki zomthi ezilwa nokungunda kunye nee-antimicrobial, udidi lwetyuwa exutyiweyo ye-boron kunye ne-zinc, imveliso yebhaktiriya yokubola nokubola komthi inamandla athile okuthintela, kodwa ikwanozinzo oluhle lobushushu kunye nozinzo lwe-UV, ukujoyina kunokuphucula iipropati zokurhoxisa ilangatye zezinto, kodwa isixa semveliso esongeziweyo siphezulu, iindleko eziphezulu zokongeza, kwaye iipropati zoomatshini zeemveliso zomthi zeplastiki zinempembelelo embi; olunye udidi ziikhompawundi ze-arsenic eziqulethe i-organic, ukwakheka kweeplastiki kusetyenziswa kakhulu. Ngobuninzi bezongezo, ukumelana nokungunda, kunye nezinye iimpawu, kodwa ngenxa yokuba into ine-arsenic, ayifikeleli kwisiqinisekiso se-REACH kunye ne-ROSH, ngoko ke abavelisi bomthi weplastiki nabo basebenzisa kancinci.
Izinto zokuthambisa zinokuphucula iipropati zomphezulu wezinto ezidityanisiweyo zomthi ezenziwe ngeplastiki kwaye zonyuse imveliso. Izinto zokuthambisa eziqhelekileyo ezisetyenziswa kwizinto ezidityanisiweyo zomthi zeplastiki yi-ethylene bisceramide (EBS), i-zinc stearate, i-paraffin wax, i-oxidized polyethylene, njl. I-EBS kunye ne-zinc stearate zisetyenziswa kakhulu kwiintlobo zeplastiki zomthi ezenziwe ngeplastiki ezisekelwe kwi-HDPE, kodwa ekubeni ubukho be-stearate bubuthathaka isiphumo sokudityanisa se-maleic anhydride, ukusebenza kakuhle kwee-agents zokudityanisa kunye nezinto zokuthambisa kunciphisa. Ke ngoko, iintlobo ezintsha zezithambiso zisaphuhliswa.
Ukusebenza kakuhle kuhambelana nokuzinza:Izithambisi ezisebenza kakuhle kakhulu ze-WPC enobuhlobo nendalo！
To ukujongana nengxaki ye-lubricant ye-composites yomthi-plastikiimakethi, i-SILIKE iphuhlise uthotho lweii-lubricants ezikhethekileyo zezinto ezidityanisiweyo ngomthi-plastiki (ii-WPC)
Le mveliso yi-silicone polymer ekhethekileyo, eyenzelwe ngokukodwa izinto ezidityanisiweyo zomthi-plastiki.
