Izinhloso Ezingafani Zama-Caster Ezingafani

I-Polyurethane eyaziwa kakhulu njenge-glue ephezulu, i-spring glue, igama eliphelele: i-polyurethane noma i-isocyanate polymer. I-Polyurethane iyielastomer phakathi kweplastiki ne-rubber, futhi izici zayo ezinhle zokuhlanganisa azitholakali kuma-plastiki ajwayelekile nase-rubber.

1. Izici ze-polyurethane casters

I-elastomer ye-polyurethane casters inezici ezinhle ezifana nokumelana nokugqoka, ukumelana nokugqwala kwemichiza, amandla aphezulu, ukujula okuphezulu, ukumelana nengcindezi ephansi, ukumelana nokushayisana okuqinile, ukumelana nokuphuka, ukumelana nokukhanya, ukwakha umthwalo ophakeme nokumelana nokushayisana. Amathayi e-polyurethane nawo anobubanzi obubanzi bokhardness, ukusuka ku-Shore A10-100.

Okwamanje, sekuvele imikhiqizo emakethe edlula i-Shaw A100 naphezulu. Ngaphezu kwalokho, ama-casters e-polyurethane anekhono elihle lokumunca umsindo, futhi amavolumu awakhiqizi umsindo ngesikhathi sokuhamba, okungafinyelela umphumela wokuthula. Lezi zici zamawheel e-PU zilungele kakhulu njengemathiriyeli ama-caster.

2. Ama-caster e-polyurethane angasebenza ngezindlela ezihlukahlukene:

(1) I-casters ye-polyurethane ingakhiqizwa ngokufaka, ukukhipha, ukuhlela, ukujija nokunye okwenziwa njengokwenziwa kweplastiki ejwayelekile (okukhuluma nge-CPU);

(2) I-polyurethane caster elastomers zingakhiqizwa futhi ngokwenza i-plasticizing, mixing kanye ne-vulcanization processes njenge-rubber ejwayelekile (bheka ku-MPU);

(3) I-casters ye-polyurethane ingakwenziwa nange-rubber ye-liquid, ukucastisa nokumoldinga noma ukushaya, ukugxila, ukucindezela (okukhuluma nge-CPU).

3. Umkhathi wokusebenzisa ama-casters e-polyurethane:

Kufaneleka ukusetshenziswa ezindaweni ezahlukene; kusetshenziswa kakhulu embonini yezokwelapha, embonini yokucubungula ukudla, ekuphathweni kwefektri, ezokugcina impahla nezokuthutha, ekwenzeni imishini, njll.; ibanga lokushisa lokusebenza liphakathi kuka -35~80℃.

◆I-Polypropylene (PP) ama-casters

PP plastic, igama le-chemistry: polypropylene. I-PP inokuqina okuhle kokushisa, izinga lokushintsha kokushisa kwayo lingu-80-100 ℃, ingaphekwa emanzini abilayo, inokuqina okuhle kokuphuka ngenxa yokucindezela, futhi inempilo yokuphenduka ephezulu, eyaziwa kakhulu ngokuthi "Bai Zhe glue", inokuqina okuhle, inokuqina okuhle kwe-chemistry.

1. Izinzuzo ze-polypropylene casters

(1) Izinto ezingalimazi, ezinganambitheki, ezilungele imvelo, eziphinde zisetshenziswe;

(2) Inemikhawulo yokumelana namafutha, ukumelana ne-asidi nokumelana ne-alkali, futhi izixazululo ezivamile ze-organic ezifana ne-asidi ne-alkali zinefuthe elincane kuyo;

(3) Inezici ezinjengokuthi iqinile, inamandla, iyakwazi ukumelana nokukhathala nokuphuka ngenxa yokucindezela, futhi ukusebenza kwayo akuthinteki yizimo zokunisela;

(4) Inenhlanhla yentengo ephansi.

2. Umkhathi wokusebenzisa ama-casters e-polypropylene:

Ifanele ukusetshenziswa ezindaweni ezahlukene; isetshenziswa kabanzi ekuphathweni kwefektri, ezindaweni zokugcina impahla nasezokuthutha, ekwenziweni kwemishini nakwezinye izimboni; ibanga lokusebenza lokushisa liphakathi kuka -15~80 °C.

◆I-Nylon (PA) ama-casters

Nylon (Nylon, Polyamide, PA ngokufushane) ibhekisela kuphulasitiki eyakhiwe ngama-resin e-polyamide. Ama-resin anjalo angalungiswa ngokuhlanganiswa kwe-diamines nama-dibasic acids, noma ngokuvulwa kwemijikelezo ye-polymerization ye-lactams eyakhiwe ngemuva kokomisa ama-amino acids.

1. Izinzuzo ze-nylon PA ama-casters

(1) Amandla aphezulu emishini, ubunzima obuhle, amandla aphezulu okudonsa nokucindezela;

(2) Ikhono lokumunca umshoshaphansi nokucindezela kukhulu, futhi amandla okuphazamiseka aphezulu kakhulu kunezinto ezivamile zeplastiki;

(3) Iphuzu eliphezulu lokuthambisa, ukumelana nokushisa, lingasetshenziswa isikhathi eside ku-150 ℃; ama-casters e-nylon aphezulu asheshiswe ngengilazi, izinga lokushintsha kokushisa lingafinyelela ngaphezulu kuka-250 ℃;

(4) Umphetho opholile, i-coefficient encane yokuphazamiseka, ukumelana nokugqoka, umsindo ophansi nokumelana okuhle kakhulu nokukhathala;

(5) Iself-extinguishing, ayinabungozi, ayinaphunga, inezinga elihle lokumelana nezimo zokukhanya, ingena emiphumeleni ye-biological, futhi inezinga elihle lokumelana namagciwane kanye ne-mildew.

2. Umkhathi wokusebenzisa ama-casters e-nylon:

Kufanele kusetshenziswe ezindaweni ezahlukene; kusekelwe kakhulu ekuphathweni kwefektri, ukugcinwa kwezimpahla kanye nezokuthutha, ukukhiqizwa kwemishini nezinye izimboni; ibanga lokushisa elijwayelekile lingu -35~180 °C; i-nylon eshisayo ingasetshenziswa endaweni eshisayo engu-250 °C.

◆Izakhi ze-artificial rubber (TPR)

Ishubhu esenziwe ngamakhemikhali iyinhlayiya ye-thermoplastic elastomer, okuyinto impahla enezici zeshubhu nezokwenziwa kabusha, engakwazi ukucubungula imikhiqizo yeshubhu ngokushesha, kahle nangokonga njengokwenziwa kabusha, futhi yaziwa njenge-shubhu eyenziwe ngokuqondile.

Izakhi ze-synthetic rubber casters zineziqu eziyinqaba ezilandelayo:

1. Ukusebenza okuhle kokuthambisa nokumelana nokushayisana, okungavikela kangcono imishini, impahla nezitezi;

2. Ukumelana okuhle kakhulu nomthelela, kudlula kakhulu i-cast iron core rubber wheel; ukusebenza kahle kokukhumbula ukwakheka okuphezulu, i-wheel ayilula ukujolisa uma imishini ibekwe ngaphansi komthwalo isikhathi eside;

3. Ukusebenza kahle, akukho noise; akukho ukugqwala, ukumelana nezinye izixazululo zamakhemikhali, amanzi kanye ne-steam;

4. Ukumelana okuhle nokugqoka, okufana nezinsimbi ze-polyurethane; isakhiwo samakhemikhali esiqinile nesinzima sokuhamba siqinisekisa ukusebenza okujwayelekile nokujikeleza mahhala kwemishini;

5. Ukumelana nokuphuka, kungasetshenziswa emhlabeni onensimbi yensimbi, amatshe, njll.
