Izvesten sposob zashchity vnutrenney ra bochey poverxnosti gidrotsiklon fasonnym kamennym litem. Futerovku osushchestvlyayut 1O ukladkoy i zakrepleniem v korpuse gidrotsiklona s pomoshchyu tsementnogo rastvora otdelnyh nabornyx kamneltyx elementov. Nedostatki bu sposoba vĐ” vysokaya trudoemkost montaj elementov iz-za netochnosti katta geometrik shakllar, katta trudnosti demontaja iznoshennoy futerovki. Otklonie ot pravilnoy geometri kamnelitoy futerovki vyzyvaet neravnomernyy iznos rabochey poverxnosti gidrotsiklona, uhudshaet texnologicheskie pokazateli ego raboty, snijaet srok slujby futerovki v tselom.
B mohs, RBSiC keramika prevyshaet 9, kotoryy blizok k tverdosti almazov.srok slujby sic keramika – v 10 dan katta, chem u poliuretanovoy obolochkoy.
ZPC razrabatyvaet va proizvodit vysokoeffektyvnye tsiklony, gidrotsiklonnye, gidrotsiklonnye vkladyshi va vspomogatelnye komponentlar o'z ichiga o'tkazuvchanlik keramicheskyh materiallardan foydalanish uchun ekstremal abrazivnyh va agressiv sredah.
Prodvinutaya keramika RBSiC s tverdostyu to 3500 Vickers bir necha oddiy materiallardan iborat bo'lib, uni o'z ichiga oladi. Oni znachitelno bolee iznosostoykie, chem nerjaveyushchie stali, ni-tverdye va stellitovye materiallar, traditsionno ispolzuemye pri proizvodstve etix tipov gidrotsiklonov.

Shandong Zhongpeng Special Ceramics Co., Ltd Xitoydagi eng yirik silikon karbidli keramik yangi material echimlaridan biridir. SiC texnik keramika: Mohning qattiqligi 9 (New Mohning qattiqligi 13), eroziya va korroziyaga mukammal qarshilik, mukammal aşınma - qarshilik va oksidlanishga qarshi. SiC mahsulotining xizmat qilish muddati 92% alumina materialidan 4-5 baravar ko'p. RBSiC ning MOR ko'rsatkichi SNBSC dan 5-7 baravar ko'p, undan murakkabroq shakllar uchun foydalanish mumkin. Kotirovka jarayoni tez, yetkazib berish va'da qilinganidek va sifat hech kimdan kam emas. Biz doimo maqsadlarimizga intilamiz va qalbimizni jamiyatga qaytaramiz.
