Yazisa:
I-PVC (i-polyvinyl chloride) i-polymer ye-thermoplastic eqhelekileyo esetyenziselwa iinjongo zoshishino kunye nezasekhaya. Ilothe, isinyithi esinobuthi esinetyhefu, isetyenziswe kwintambo ye-PVC iminyaka emininzi, kodwa iziphumo zayo ezimbi kwimpilo yabantu kunye nokusingqongileyo kuye kwakhokelela ekuphuhliseni ezinye iindlela zePVC. Kweli nqaku, siza kuxoxa ngomahluko phakathi kwePVC kunye nePVC engenanto.
Yintoni iPVC engaKhokheli?
I-PVC engakhokhelwa luhlobo lwePVC olungenayo nayiphi na ilothe. Ngenxa yokungabikho kwelothe, iPVC engenalothe ikhuselekile kwaye inobuhlobo nokusingqongileyo kunePVC yesintu. I-PVC engenalothe idla ngokwenziwa nge-calcium, i-zinc okanye i-tin stabilizers endaweni ye-lead-based stabilizers. Ezi zinzisi zineepropati ezifanayo njenge-lead stabilizers, kodwa ngaphandle kwemiphumo emibi kwimpilo kunye nokusingqongileyo.
Umahluko phakathi kwePVC kunye nePVC ekhokelayo
1. Ubutyhefu
Umahluko ophambili phakathi kwePVC kunye nePVC engakhokhelwa bubukho okanye ukungabikho kwelothe. Iimveliso ze-PVC zihlala zinezinzisi ezikhokelayo ezinokuphuma kwizinto eziphathekayo kwaye zibangele umonakalo wokusingqongileyo. Ilothe sisinyithi esinzima esinetyhefu enokubangela iingxaki zemithambo-luvo nophuhliso, ngakumbi ebantwaneni. I-PVC engenalo ilothe isusa umngcipheko wokwakheka kwelothe.
2. Impembelelo yokusingqongileyo
I-PVC ayiboli kwaye inokuhlala kwimo engqongileyo amakhulu eminyaka. Xa itshisiwe okanye ilahlwa ngendlela engafanelekanga, iPVC inokukhupha imichiza eyityhefu emoyeni nasemanzini. I-PVC engenalothi ihambelana nokusingqongileyo kuba ayiqulathanga ilothe kwaye inokuphinda isetyenziswe.
3. Iimpawu
I-PVC kunye ne-PVC engenalo i-lead-free ineempawu ezifanayo, kodwa kukho ukungafani. I-Lead stabilizers inokuphucula iimpawu zePVC ezifana nokuzinza kwe-thermal, isimo sezulu kunye nokuqhubekeka. Nangona kunjalo, i-PVC engenalo i-lead inokufikelela kwiipropati ezifanayo ngokusebenzisa iziqinisekiso ezongezelelweyo ezifana ne-calcium, i-zinc kunye ne-tin.
4. Iindleko
I-PVC engenalo i-lead inokubiza ngaphezu kwe-PVC eqhelekileyo ngenxa yokusetyenziswa kwezinzisi ezongezelelweyo. Nangona kunjalo, umahluko weendleko awubalulekanga kwaye izibonelelo zokusebenzisa i-PVC engenalo i-load yodlula iindleko.
