1. YiniIphepha Letshe?

Iphepha letshe lenziwe ngemithombo yamaminerali e-limestone enezinqolobane ezinkulu kanye nokusatshalaliswa okubanzi njengezinto ezingavuthiwe eziyinhloko (okuqukethwe kwe-calcium carbonate kungu-70-80%) kanye ne-polymer njengento eyisizayo (okuqukethwe yi-20-30%). Ngokusebenzisa isimiso se-polymer interface chemistry kanye nezici zokuguqulwa kwe-polymer, iphepha lamatshe lenziwa nge-polymer extrusion kanye nobuchwepheshe obuvuthelayo ngemva kokucubungula okukhethekile. Imikhiqizo yephepha lamatshe inokusebenza okufanayo kokubhala kanye nomphumela wokuphrinta njengephepha lefiber yezitshalo. Ngesikhathi esifanayo, inezakhiwo eziyinhloko zokupakishwa kwepulasitiki.

2. Izici ezibalulekile zephepha lamatshe?

Izakhiwo zephepha zamatshe ezihlanganisa ukuphepha, ngokomzimba, nezinye izici, futhi izici eziyinhloko azinamanzi, zivimbela inkungu, zivimbela amafutha, izinambuzane, njll.

Ukuphrinta kwephepha lamatshe ngeke kuqoshwe ngencazelo ephakeme, kuze kufike ku-2880DPI ngokunemba, indawo engaphezulu ayimboziwe ngefilimu, ngeke ibe nesenzo samakhemikhali ngoyinki, okuzogwema ukwakheka kombala noma isenzakalo se-decolorization.

3. Kungani sikhetha iphepha lamatshe?

a. Inzuzo yezinto ezibonakalayo. Iphepha lendabuko lokudla ukhuni oluningi, futhi iphepha lamatshe liyimithombo yamaminerali eningi kakhulu oqweqweni lomhlaba lwe-calcium carbonate njengento eluhlaza eyinhloko, cishe u-80%, impahla ye-polymer - ukukhiqizwa kwe-petrochemical ye-polyethylene (PE) cishe ngama-20%. Uma uhlela umkhiqizo wonyaka wephepha letshe le-5400kt, izinkuni eziyizigidi ezingu-8.64 m3 zingasindiswa minyaka yonke, okulingana nokunciphisa ukugawulwa kwamahlathi ngamakhilomitha-skwele angu-1010. Ngokwenqubo yendabuko yokusetshenziswa kwamanzi ka-200t ngethani lephepha, ukukhishwa kwaminyaka yonke kwamathani ayizigidi ezingu-5.4 wephrojekthi yephepha lamatshe kungasindisa amathani ayizigidi ezingu-1.08 zemithombo yamanzi njalo ngonyaka.

b. Izinzuzo zemvelo. Yonke inqubo yokukhiqiza amatshe amaphepha awadingi amanzi, uma kuqhathaniswa nokwenza iphepha okuvamile kususa ukupheka, ukuwasha, ukuxubha nezinye izinyathelo zokungcola, ngokuyisisekelo ukuxazulula imfucuza yemboni yokwenza iphepha. Ngaso leso sikhathi, iphepha letshe eligaywe kabusha lithunyelwa endaweni yokushiswa ukuze lishiswe, elingeke likhiphe intuthu emnyama, kanti impushana esele yamaminerali angabuyiselwa emhlabeni nasemvelweni.

Ukwenziwa kwamaphepha ngamatshe kusindisa kakhulu izinsiza zehlathi nemithombo yamanzi, futhi ukusetshenziswa kwamandla kweyunithi kuyi-2/3 kuphela yenqubo yendabuko yokwenza iphepha.
