iimveliso

Kwiminyaka yakutshanje, izinto ezilula, ezinekhabhoni ephantsi, kunye nokusebenza okuphezulu ziye zaba zizihloko ezintathu eziphambili kushishino lokuvelisa. Nangona izixhobo zesinyithi zemveli zinamandla aphezulu, zinoxinano olukhulu, ukusetyenziswa kwamandla aphezulu okucubungula, kwaye zisengozini yokugqwala; Nangona iiplastiki eziqhelekileyo eziqinisiweyo zefayibha yeglasi emfutshane zinemiphumo ebalulekileyo yokunciphisa ubunzima, azisebenzi kakuhle phantsi kweemfuno ezifana nomthamo wokuthwala umthwalo ixesha elide, ukutshintshana kwamaqondo obushushu aphezulu naphantsi, kunye nokuqina okuphezulu okuneendonga ezincinci.

Kukule meko apho i-polypropylene eqinisiweyo yefayibha ende yeglasi (LGF-PP) kunye ne-polyamide eqinisiweyo yefayibha ende yeglasi (LGF-PA66) zibonakala njengenye yeendidi ezikhula ngokukhawuleza kwicandelo leplastiki elungisiweyo kwihlabathi liphela. Ngokwezibalo zoshishino, ubungakanani bemarike yehlabathi yee-composites ze-thermoplastic eziqinisiweyo zefayibha ende yeglasi kulindeleke ukuba bukhule ukusuka kwi-2.8 yeebhiliyoni zeedola zaseMelika ngo-2023 ukuya kwi-4.5 yeebhiliyoni zeedola zaseMelika ngo-2030, kunye nesantya sokukhula sonyaka esidibeneyo esimalunga ne-7.2%, ikakhulu siqhutywa yimithetho elula kunye noxinzelelo lweendleko.

一,Iingenelo eziphambili zobuchwepheshe bezinto eziqinisiweyo zeglasi ende

Ngokungafaniyo neeplastiki ezimfutshane eziqinisiweyo ngefayibha yeglasi (ngesiqhelo ubude bayo buyi-0.2-0.6mm), izinto ezinde eziqinisiweyo ngefayibha yeglasi zigcina ubude befayibha yeglasi obuyi-10-25mm kwi-resin matrix ngokusebenzisa iinkqubo ezikhethekileyo zokufaka kunye nokukhupha, kwaye zenze isakhiwo senethiwekhi esinemilinganiselo emithathu emva kokubumba ngenaliti. Kufuneka kuqatshelwe ukuba izinga lokugcina olu lwakhiwo lwenethiwekhi lixhomekeke kuyilo lwezikrufu kunye nefom yesango ngexesha lokubumba ngenaliti; Ukuba inkqubo ayifanelekanga, ubude be-fiberglass busenokuncipha kakhulu.

Olu lwakhiwo luzisa uphuculo oluphambili lwentsebenzo ezintathu:

1. Ukumelana nempembelelo ephezulu kakhulu

Inethiwekhi yefayibha yeglasi ende inokuthintela ngempumelelo ukwanda kweentanda, kwaye amandla ayo okuchaphazela nge-notch aphezulu ngama-40% -80% kunalawo efayibha emfutshane ye-PP/PA. Kubushushu obuphantsi be--40 ℃, izixhobo eziqhelekileyo zisengozini yokuqhekeka, ngelixa izixhobo zefayibha yeglasi ende zisenokugcina ngaphezulu kwe-80% yokusebenza kwazo kokuchaphazela kubushushu begumbi. Idatha engentla isekelwe kwimigangatho yovavanyo ye-ISO 179 okanye ye-ASTM D256.

2. Ukumelana okuhle kakhulu nokuqhekeka kunye nozinzo olunemilinganiselo

Phantsi kwemithwalo engashukumiyo yexesha elide (njengeefreyimu zemoto kunye nemilenze yokuxhasa izixhobo zasekhaya), izinto zefayibha ezimfutshane ziya kudlula kwinguquko enkulu yokuqhekeka, ngelixa izinto zefayibha zeglasi ende ziya kuba nesantya sokuqhekeka esincitshiswe ngaphezulu kwama-50% ngenxa yokuxhaswa yi-skeleton yefayibha yeglasi. Okwangoku, kwiimvavanyo zokujikeleza kobushushu obuphezulu nobuphantsi ukusuka kwi--40 ℃ ukuya kwi-120 ℃, ukuguquka kwe-warpage yeemveliso zefayibha yeglasi ende kumalunga nesinye kwisithathu seefayibha ezimfutshane. Oku kwenza izinto ze-LGF zifaneleke ngokukodwa kwiindawo ezinokuguquguquka okukhulu kobushushu bangaphandle.

3. Ubunye bamandla aphezulu kunye nokukhanya okuncinci

Uxinano yi-1/2-1/3 kuphela ye-aluminium alloy (i-LGF-PP imalunga ne-1.0-1.2 g/cm³, i-LGF-PA66 imalunga ne-1.3-1.5 g/cm³), kodwa amandla athile (amandla/uxinano) asondele okanye adlule nalawo e-aluminium alloys, nto leyo eyenza ukuba ibe lolona khetho lufanelekileyo lokufikelela "ekutshintsheni intsimbi ngeplastiki". Umzekelo, amandla okutsalwa kwe-LGF-PP40 anokufikelela kwi-120-150 MPa, kwaye i-bending modulus inokufikelela kwi-10-12 GPa, eyaneleyo ukutshintsha iintsimbi kwiindawo ezininzi ezakhiwe kancinci.

二,Iindawo eziqhelekileyo zokusetyenziswa kunye neemfuno ezithile zezixhobo kwicandelo ngalinye

Imizekelo yecandelo loshishino, iimfuno eziphambili, izixhobo ezicetyiswayo

三Idatha yeNdlela yeMarike

Ngokwezibalo zabantu besithathu, ubungakanani bemarike yehlabathi yee-long glass fiber reinforced thermoplastic composites kulindeleke ukuba ifikelele kwi-2.8 yeebhiliyoni zeedola zaseMelika ngo-2023, kwaye kulindeleke ukuba ifikelele kwi-4.5 yeebhiliyoni zeedola zaseMelika ngo-2030, kunye nesantya sokukhula kwe-compound yonyaka se-7.2%. Umthombo wedatha: Iingxelo zoshishino ezifana neMarketsandMarkets. Phakathi kwazo, ummandla we-Asia Pacific unesantya sokukhula esikhawulezayo, kwaye iTshayina, njengomvelisi omkhulu kunye nomthengisi weplastiki oguquliweyo, ngokuthe ngcembe ithatha indawo yezinto eziluhlaza ezibizayo zaseYurophu naseMelika. Amandla aphambili okuqhubayo yinzuzo yeendleko (20% -30% iphantsi kuneempawu zaseYurophu naseMelika) kunye nemijikelo emifutshane yokuhambisa.

四、 Indawo yethu

Inkampani yethu ibigxile kuphando kunye nemveliso ye-LGF-PP kunye ne-LGF-PA66 kangangeminyaka engaphezu kwama-20, kwaye inenkqubo ezimeleyo yenkqubo yobuchwepheshe obuqhubekayo bokufaka ifayibha yeglasi ende. Le mveliso ithunyelwe ngobuninzi eYurophu, eRashiya, eMzantsi-mpuma Asia, eMbindi Mpuma, eMzantsi Melika nakwezinye iindawo.

Asizibangi njengeyodwa okanye eyona ilungileyo, kodwa sinikezela ngezinye iindlela eziqinisekisiweyo. Xa kuthelekiswa neempawu eziphambili zaseYurophu naseMelika ezifana neSABIC, iCelanese, kunye neDSM, inzuzo yethu eqhelekileyo yeendleko yi-20% -25%, ngelixa sigcina i-85% -95% yokusebenza kwayo koomatshini, okuye kwaqinisekiswa ngovavanyo lwebhetshi ngabathengi abaninzi.

Asiboneleli ngamabakala aqhelekileyo kuphela, kodwa sikwalungiselela iifomyula ngokweendawo abathengi abazisebenzisayo (amaqondo obushushu aphezulu naphantsi, ukufuma, amabala eoyile, ukuvezwa ngaphandle), sinceda abathengi ukunciphisa kakhulu iindleko zezinto ngelixa beqinisekisa ukusebenza kakuhle.Amava asebenzisekayo: Iifomula ezenzelwe wena zihlala zifuna iiveki ezi-4-6 zokulungiswa kwefomula kunye nokuqinisekiswa kwesampuli ngaphambi kokuba ziqale ukuvelisa ngobuninzi.
