I-Fiberglass Chopped Strand Mat: Ukuvelisa, Iimpawu, kunye nezicelo

I-Fiberglass inqunyulwe i-strand mat (CSM)sisixhobo esomelezayo esisetyenziswa ngokubanzi kushishino lwecomposites. Iveliswe ngokusikai-fiberglass rovings eqhubekayokwimisonto engama-50mm ubude, ezi ntsinga zisasazwa ngokungenamkhethe kwaye zibekwe kwibhanti yokuhambisa intsimbi engenastainless. I-mat idityaniswe kusetyenziswa i-emulsions yolwelo okanye izibophelelo ezinomgubo, zilandelwa yi-high-temperature yomisa kunye neenkqubo zokupholisa ukwenza nokuba yi-emulsion-bond okanye i-CSM edibeneyo yomgubo. Le ndlela yokuvelisa iqinisekisa ukuhanjiswa kobunzima obufanayo, imiphezulu egudileyo, kunye nemfezeko yolwakhiwo, iyenza ibe lukhetho olukhethwayo kwizinto ezahlukeneyo.izicelo zoshishino.

Iimpawu eziphambili kunye nezinto eziluncedo

1. Ukomelezwa okufanayo: I-random, i-isotropic yokusabalalisa iifayili zeglasi zibonelela ngeempawu zomatshini ezilungeleleneyo kuzo zonke iinkalo, ukuphucula ukusebenza kwesakhiwo seemveliso ezidibeneyo.

2. Ukuhambelana okuPhezulu: I-CSM ibonisa ukuguquguquka okugqwesileyo kokungunda, ivumela usetyenziso olungenamthungo kwiijometri ezintsonkothileyo ngaphandle kokufuduswa kwefayibha okanye imiphetho eyophukayo. Olu phawu lubalulekile kuyilo oluntsonkothileyo kwiindawo zemoto okanye ufakelo lobugcisa.

3. Ukuhambelana kweResin ephuculweyo: Ukufunxa i-resin ephuculweyo kunye neempawu zokuphuma ngokukhawuleza ezimanzi zinciphisa ukubunjwa kwe-bubble ngexesha lokutshisa. Ugcino lwamandla olumanzi oluphezulu lwemat luqinisekisa ukungena okusebenzayo kwentlaka, kucutha inkcitho yezinto eziphathekayo kunye nexesha labasebenzi.

4. Ukuguquguquka kwiNkqubo: Ukusikwa ngokulula kunye nokwenza ngokwezifiso, i-CSM ithatha iindlela ezenziwe ngezandla okanye ezenziwe ngoomatshini ngelixa igcina ubukhulu obungaguqukiyo kunye nomgangatho womphetho.

Izicelo zoShishino

I-CSM isebenza njengesiseko semathiriyeli kumacandelo amaninzi:

-Ezothutho: Isetyenziswa kakhulu kwizikhephe zesikhephe, iiphaneli zemoto (umzekelo, iibhampa), kunye nezixhobo zikaloliwe ngenxa yokuxhathisa umhlwa kunye nomlinganiselo ophezulu wokuqina kobunzima.

- Ukwakhiwa: Ifakwe kwi-GRG (i-gypsum eyomelezwe ngeglasi), izixhobo zococeko (iibhafu, iindawo ezivaliweyo zeshawari), kunye neenkqubo zomgangatho ochasene nomhlwa.

- Amandla kunye nezibonelelo: Isetyenziswa kwimibhobho ekwaziyo ukumelana neekhemikhali, iileya zokugquma umbane, kunye namalungu einjini yomoya.

- Amashishini okudala: Ithandwe kwimizobo eqingqiweyo, iipropu zethiyetha, kunye neemodeli zoyilo ezifuna ubulula kodwa omelele.

Iindlela zokuSebenza

1. UkuLay-Up kwezandla: Njengeyona ndlela iphambili kwishishini laseTshayina le-FRP, ukubekwa kwezandla kuncedo kwi-CSM yokugcwala ngokukhawuleza kwentlaka kunye nesakhono sokususwa kweqamu. Ulwakhiwo lwalo lwenza lula ukugquma komngundo, lunciphisa amanyathelo omsebenzi kwiimveliso ezinkulu ezifana namadama okuqubha okanye iitanki zokugcina.

2. Ukujika kweFilament: I-CSM kunye neemethi ze-strand eziqhubekayo zenza i-resin ecebileyo yangaphakathi / yangaphandle umaleko kwimibhobho okanye kwiinqanawa zoxinzelelo, ukuphucula umphezulu kunye neempawu zokuthintela ngokuchasene nokuvuza.

3. I-Centrifugal Casting: I-CSM ebekwe ngaphambili kwi-molds ejikelezayo ivumela ukungena kwe-resin phantsi kwamandla e-centrifugal, ilungele ukuvelisa amacandelo e-cylindrical angenamthungo kunye ne-voids encinci. Le ndlela ifuna iimethi ezinokungena okuphezulu kunye nokuthathwa kwe-resin ngokukhawuleza.

IiNgcaciso zobuGcisa

- Iintlobo zeBinder: Iimethi ezisekelwe kwi-emulsion zinika ukuguquguquka kweendawo ezigobileyo, ngelixa i-powder-bonded variants iqinisekisa ukuzinza kwe-thermal kwiinkqubo eziphezulu zokunyanga ukushisa.

- Ubunzima Uluhlu: Iimethi ezisemgangathweni zisusela kwi-225g/m² ukuya kwi-600g/m², zilungelelaniswa neemfuno zobukhulu.

- Ukumelana nemichiza: Iyahambelana ne-polyester, i-vinyl ester, kunye ne-epoxy resins, i-CSM ihambisa i-asidi engaqhelekanga / ukumelana ne-alkali kwiindawo zaselwandle kunye neekhemikhali.

Ukuqukumbela

I-Fiberglass inqunyulwe ye-strand mat ibhulorho yokusebenza kunye nokusebenza kwimveliso edibeneyo. Ukulungelelaniswa kwayo kwiindlela ezininzi zokusetyenzwa, ezidityaniswe neendleko-zokusebenza kunye nokuthembeka koomatshini, ibeka njengesixhobo esiyimfuneko kumashishini abeka phambili ukuqina kunye nobunzima boyilo. Inkqubela phambili kwitekhnoloji ye-binder kunye nonyango lwefayibha iyaqhubeka nokwandisa usetyenziso, iqinisa indima yayo kwizisombululo zobunjineli ezikhaphukhaphu kwisizukulwana esilandelayo. Nokuba yeyamalungu eemoto eziveliswe ngobuninzi okanye izinto zoyilo lwe-bespoke, i-CSM ihlala ililitye lembombo lokwenziwa kwangoku okuyintlanganisela.
