Ngokumalunga nephepha, umbuzo osoloko ubuzwa ngabathengi ngowokuba, ngaba uyalithengisa iphepha le-A4?

Kubonakala ngathi ukuqonda koluntu ngeemveliso zephepha kuhlala kuphela kwiphepha lethu lokushicilela elisetyenziswa ngokuqhelekileyo, iincwadi zamanqaku kunye nezinye iimveliso zasekuhlaleni.Kodwa namhlanje siza kuzisa uhlobo lwephepha ongazange uve ngalo ngokunokwenzeka okuphezulu - iphepha elingenaso sulfure.

Xa sithetha ngegama lephepha le-sulfur-free, ukuba awuzange ulichukumise, unokuzibuza umbuzo.Ngaba kukho unxibelelwano phakathi kwesalfa nephepha?

Oku kumalunga nokuveliswa kwephepha langoku.Kwinkqubo yokwenza iphepha lephepha lanamhlanje, into ebaluleke kakhulu engabonakaliyo idla ngokusetyenziswa - i-aluminium sulfate (elinye igama layo yi-alum)

Iimveliso zephepha zongeza i-aluminium sulfate njenge-arhente yokulinganisa kwinkqubo yokwenziwa kwephepha, inika iphepha lokuchasa ukunxiba, ukuchasana namanzi, ukuchasana ne-emulsion, iipropathi zokulwa nokubola, kwaye kwangaxeshanye kuphuculwe ukuguda kwephepha kunye nokulinika amanzi- ukuziqhelanisa noshicilelo.

Kule nkqubo, akunakuphepheka ukuba iimveliso zephepha eziveliswayo ziya kuba nesulfure.

Nangona kunjalo, kwezinye iimeko zokusebenzisa i-industrial high-end civil, umxholo wesulfure ephepheni kufuneka ulawulwe ngaphakathi kwinqanaba eliphantsi kakhulu.

Bejongene nale mfuno, oomatshini bephepha baqhubeka bezama ukuphucula inkqubo yokuvelisa iphepha, yaye ekugqibeleni kwazalwa iphepha elingenasalfure.

Amaphepha asetyenziswa kwiinkalo ezahlukeneyo aneyantlukwano yawo, njengephepha lemizi-mveliso kunye nephepha lendlu.

Iphepha lemizi-mveliso elifana nephepha lokushicilela, iphepha elingenasulphur, iphepha lokufunxa ioli, iphepha lokusonga, ikraft paper, iphepha elingangenwa luthuli, njl. njl., iphepha lasendlini njengeencwadi, napkins, amaphephandaba, indlu yangasese, njl.

Makhe sichaze umahluko phakathi kwephepha elingenasalfa nephepha lethu eliqhelekileyo elisetyenziswa ngokuqhelekileyo.

Si-ulfur-free iphepha

Iphepha leSulfur-free liphepha elixhasayo elikhethekileyo le-PCB yesilivere kubenzi bebhodi yesekethe.Ingqiqo ephambili yokusebenzisa olu hlobo lwephepha kukuphepha ukuphendulwa kweekhemikhali zesilivere ngesulfure emoyeni, okubangela ukuba iphenduke iphuzi.Kwaye ukusetyenziswa kwephepha elingenayo isulfure kunokuphepha ukusabela phakathi kwesulfure kunye nesilivere, nto leyo enokukhokelela kwezinye iziphene zepcb.

Kwangaxeshanye, iphepha elingenasalfure likwanqanda ukusabela kweekhemikhali phakathi kwesilivere ekwimveliso egqityiweyo ye-electroplating kunye nesalfure esemoyeni, okukhokelela ekubeni imveliso ijike ibe tyheli.Ngoko ke, imveliso kufuneka ifakwe ngephepha le-sulfure ngokukhawuleza emva kokuba imveliso igqityiwe, kwaye iiglavu ezingenayo i-sulfure kufuneka zigqitywe xa zichukumisa umkhiqizo, kwaye akufanele zithintele indawo ye-electroplated.

Iimpawu zephepha le-sulfur-free: iphepha elingenaso sulfure licocekile, alinathuli, i-ROHS-ithobela, ayinayo isulfure (S), i-chlorine (CL), i-lead (Pb), i-cadmium (Cd), i-mercury (Hg), i-hexavalent chromium (CrVI), i-polybrominated biphenyls kunye ne-polybrominated diphenyl ethers.Ingasetyenziswa ngcono kwibhodi yesekethe yePCB kwishishini lombane kunye ne-hardware electroplating industry.

Ukusetyenziswa kwephepha leSulfur-free: ikakhulu esetyenziselwa ukupakishwa kwesilivere, okufana neebhodi zesekethe, ii-LED, iibhodi zesekethe, iitheminali zehardware, iimveliso zokhuseleko lokutya, ukupakishwa kweglasi, ukupakishwa kwehardware, ukwahlula ipleyiti yentsimbi, ukupakishwa kokutya, njl.
