Waa maxay Dahaarka budada Thermoplastic

Heerkulbeegga dusha budada dhalaaliya oo ku qulqula codsiga kulaylka, laakiin waxay sii wadaa inay lahaato isla halabuurka kiimikada marka ay ku adkaysato qaboojinta. Dahaarka budada Thermoplastic waxay ku salaysan tahay xabagta-thermoplastic ee miisaanka unugyadu sareeyo. Tilmaamaha dahaarkani waxay ku xiran yihiin sifooyinka aasaasiga ah ee resin. Resins-yadan adag iyo kuwa adkaysiga leh waxay u muuqdaan inay noqdaan kuwo adag, iyo sidoo kale qaali, si ay u noqdaan qaybo aadka u fiican ee lagama maarmaanka u ah codsiga buufinta iyo isku darka filimada khafiifka ah. Sidaa awgeed, hababka resin thermoplastic waxa loo isticmaalaa in badan sida dahaar shaqaynaya oo dhumucdiisuna tahay mils badan waxaana badanaa lagu dabaqaa farsamada codsiga sariiraha dareeraha ah.

Tusaalooyinka caadiga ah ee dahaarka budada thermoplastic waa:

polyetylen

Budada polyetylen waxay ahaayeen dahaarka budada thermoplastic ee ugu horeysay ee la siiyo warshadaha. Polyethylene waxay bixisaa dahaarka caabbinta kiimikaad aad u wanaagsan iyo adayg leh sifooyin koronto oo heer sare ah. Dusha sare ee dahaarka noocan oo kale ah waa siman yihiin, diirran marka la taabto, iyo dhalaal dhexdhexaad ah. Dahaarka polyetylenku waxay leeyihiin sifooyin wanaagsan oo la sii daayo, taas oo u oggolaanaysa walxaha dhejiska leh in laga nadiifiyo dusha sare. Sidaa darteed, waxay helayaan adeegsiyo badan oo daaha ah ee qalabka shaybaadhka.

Polypropylene

Sida dahaarka dusha sare, polypropylene waxay bixisaa waxyaabo badan oo faa'iido leh oo ay leedahay sida walxo balaastig ah. Sababtoo ah natural polypropylene waa mid aan fiicneyn, waxay muujineysaa in yar oo u janjeera in loo hoggaansamo biraha ama substrates kale. Sifadan ayaa lagama maarmaan ka dhigaysa in si kiimiko ah wax looga beddelo dabeecaddaral polypropylene marka loo isticmaalo sida budada dahaarka dusha sare, si ay ugu dhajinta daahan in substrate la heli karo.

nylon

Budada naylon waxay ku dhawaad ​​​​dhammaan ku saleysan yihiin nooca 11 naylon resin waxayna bixiyaan dahaar adag oo leh naax, xidhid, iyo iska caabin aad u wanaagsan oo leh iskudhaf hooseeya marka lagu dabaqo mid ku habboon. asaasiga ah. Isticmaalka ugu xiisaha badan ee daahan budada naylon waa goobta naqshadeynta farsamada. Isku darka gaarka ah ee iskudarka hoose ee is jiid jiidka iyo lubricity wanaagsan ayaa ka dhigaysa mid ku habboon silbashada iyo wareejinta codsiyada xajinta sida shafka baabuurta, tuubbada gudbinta, iyo fargeetoyada wareegyada, iyo sagxadaha kale ee kor u qaada qalabka, qalabka beeraha, iyo mashiinada dunta.

polyvinyl

Dahaarka budada ah ee chloride polyvinyl waxay leeyihiin adkeysi dibadeed oo wanaagsan waxayna bixiyaan dahaarka leh dhalaal dhexdhexaad ah oo jilicsan. Waxay si fiican ugu xidhaan substrate-yada birta badankooda marka la dul mariyo curiye ku habboon. Dahaaradahani waxay u adkeysan doonaan culayska hawlaha biraha samaynta sida foorarsiga, dhejinta, iyo sawiridda.

Polyester Thermoplastic

Dahaarka budada polyester-ka ah ee Thermoplastic waxay leeyihiin ku-dhejin wanaagsan inta badan substrate-yada birta ah iyaga oo aan u baahnayn asal, waxayna muujinayaan jawi wanaagsan oo dibadda ah. Waxay dahaar fiican u yihiin alaabta sida alaabta guriga ee birta ah.
Budada Thermoplastic waxay aad ugu habboon yihiin alaabta dahaadhka ah ee u baahan filim dhumuc weyn leh waxqabadka xad dhaafka ah. Ma hidde-sideralSi la mid ah suuqyada ay ugu tartamaan rinjiga dareeraha ah.
