Phantsi koxinzelelo olubini "lokufakelwa kombane" kunye "nolukhaphukhaphu" namhlanje'Ishishini leemoto, igram nganye egciniweyo iguqulela kuluhlu olude kunye nokusetyenziswa kwamandla okuncitshisiweyo. Nangona ingqalelo enkulu inikwa izinto ezinkulu ezifana nezakhiwo zomzimba kunye neebhetri, inxalenye ebonakala ingenamsebenzi kodwa ibalulekileyo idlula kutshintsho lwezinto eziphathekayo.—isakhelo sesihlalo semoto.
Izakhelo zezihlalo zemveli zihlala zenziwe ngentsimbi eqinisiweyo neyomeleleyo. Nangona zihlangabezana neemfuno zokuqina, zinzima kwaye zinika inkululeko yoyilo elinganiselweyo. Ngokuphucuka ngokukhawuleza kweplastiki yobunjineli, i-polypropylene ende yeglasi eqinisiweyo ngefayibha (LGF/PP) ikhawuleza ithathe indawo yesinyithi njengezinto ezifanelekileyo kwizakhelo zezihlalo zesizukulwana esilandelayo.
Yintoni i-Long Glass Fiber PP?
Ngokungafaniyo nezinto zeglasi ezimfutshane eziqiniswe ngefayibha (apho ubude befayibha buhlala bungaphantsi kwe-1 mm), i-polypropylene ende eqiniswe ngefayibha yeglasi ibhekisa kwi-composite eguquliweyo equlethe iifayibha zeglasi enobude obuyi-10–25 mm. Olu lwakhiwo lukhethekileyo lunika ithuba elihle kakhulu ekusebenzeni kwezinto:
Inethiwekhi yefayibha enemilinganiselo emithathu: Ngexesha lokubumba ngenaliti, iifayibha zeglasi ezinde ziyadibana ngaphakathi kwi-polymer matrix, zenze ulusu olunemilinganiselo emithathu. Nokuba izinto ezisisiseko zithambile kumaqondo obushushu aphezulu, inethiwekhi yefayibha inceda ukugcina imo.—into eyaziwa ngokuba yi-"fiber skeleton effect."
Ubude befayibha eseleyo ephezulu: Ubude befayibha eseleyo kwinxalenye egqityiweyo bukhulu kakhulu kunobo bezinto zesiqhelo. Le yimfihlo ephambili yokuqina kwayo okuphezulu.
Kutheni Ilungele Iifreyimu Zesihlalo?
Kwabavelisi beemoto, izihlalo azipheleli nje ekuthuthuzeleni—Zizinto zokhuseleko. Kwimeko yokungqubana, isakhelo sesihlalo kufuneka simelane namandla aqatha okubetha ngelixa sigcina ulungelelwaniso lwesakhiwo. I-LGF/PP isombulula ngokugqibeleleyo ingxabano phakathi kokuqina kunye nokuqina kwiplastiki yobunjineli:
Amandla aphezulu kunye nokumelana nempembelelo: I-LGF/PP inika amandla okutsalwa kunye ne-flexural modulus egqwesileyo, kunye nokumelana nempembelelo3–Ingaphezulu ngokuphindwe kahlanu kunezinto zeglasi ezimfutshane eziqiniswe ngefayibha. Xa iphahlazeka, ifunxa amandla amaninzi ngokuguqulwa kwayo ngaphandle kokuqhekeka okubuthathaka, ngaloo ndlela ikhusela abantu abangaphakathi.
Ukumelana kakuhle nokurhubuluza: Izihlalo ziindawo ezithwala umthwalo ezixhomekeke kuxinzelelo lwexesha elide. Nangona iiplastiki zesiqhelo zidla ngokonakala xa umthwalo uqhubeka, i-LGF/PP igcina uzinzo olulinganayo nokuba lukwi-100°C ixesha elide, ixhathisa ukuguquka okungapheliyo.
Ukunciphisa ubunzima obubonakalayo: Xa kuthelekiswa nezakhiwo zentsimbi zemveli, izakhelo zezihlalo ze-LGF/PP zifikelela kwi-20–Ukunciphisa ubunzima ngama-30%, okunceda ngokuthe ngqo ukunciphisa ukusetyenziswa kwepetroli okanye ukwandisa uluhlu lwe-EV.
Inkululeko yoyilo: I-LGF/PP ivumela ukudityaniswa kwamacandelo amaninzi esinyithi kwinxalenye enye, entsonkothileyo ebumbene ngenaliti, okwenza kube lula ukuhlanganisa nokunciphisa iindleko zezixhobo (malunga ne-20% yezo zesinyithi zokunyathela).
Izicelo zeHlabathi lokwenyani
Le nto ayisiyongcamango yelabhoratri—sele iqinisekisiwe kwiimoto ezenziwe ngobuninzi.
1: Igobolondo layo lesihlalo lisebenzisa i-thermoplastic composite eqhubekayo yefayibha eqinisiweyo yeglasi, ifikelela ekuqineni okuphezulu ngelixa igcina phantse iigram ezingama-800 xa kuthelekiswa nesakhiwo sentsimbi.
2: Imodyuli yayo yomnyango wangaphambili kunye nezixhobo zesihlalo zisebenzisa i-LGF/PP ukuze kufezekiswe ukuhlanganiswa okuphezulu kokusebenza, kunye nokusebenza okuphantsi kokuqhekeka kumaqondo obushushu aphezulu.
Imbonakalo yeTekhnoloji
Njengoko umkhwa "wokutshintsha isinyithi ngeplastiki" usiya usanda, i-LGF/PP ayisapheleli nje kwizithuthi zeenjini zokutsha zangaphakathi. Kwicandelo lezithuthi zamandla amatsha, ikhilogram nganye yokunciphisa ubunzima iyabalwa. Ngeenkqubo zokubumba inaliti ezilungisiweyo (umz., ukulawula amaqondo obushushu anyibilikayo phakathi kwe-190).°C kunye nama-250°C), amandla empembelelo yezinto anokonyuswa ngaphezulu kwe-50%.
Ukongeza, inkqubela phambili kubuchwepheshe obungenavumba liphantsi kunye nobuchwepheshe obungena-VOC iphantsi yenza i-LGF/PP ibe nobuhlobo nokusingqongileyo ngakumbi, ihlangabezana nemigangatho yomgangatho womoya oqinileyo wekhabhini.
Isiphelo
Iifreyimu zezihlalo zeemoto ziyatshintsha ukusuka kwizakhelo zentsimbi ukuya kwi-polymers ezibunjiweyo. Ngenxa yokudibanisa kwayo okubalaseleyo kwamandla aphezulu, ukuqina okuphezulu, kunye nobunzima obuphantsi, i-polypropylene ende eqiniswe ngefayibha yeglasi iba yinto ekhethwayo kuyilo lwezihlalo zesizukulwana esilandelayo. Ayizisi nje kuphela iindleko zokusebenza eziphantsi kubathengi kodwa ikwabonelela ngeenjineli ngamathuba amatsha okucinga ngokutsha ngeendawo zangaphakathi zezithuthi. Kumdyarho wokwenza ukukhanya kube lula, i-LGF/PP ngokucacileyo iphakathi kwabaphambili.
