Pasirose - Premier DMF: Mushonga Unokosha weMaindasitiri Akasiyana-siyana
Minda mikuru yekushandisa
DMF inoshandiswa zvakanyanya muindasitiri yemachira. Inoshanda sechinhu chakakosha mukugadzira machira ekugadzira, akadai senylon ne acrylic. Inobatsira kunyungudutsa mapolymer precursors, zvichibvumira kudzora kwakanyatsojeka maitiro ekumonera uye zvichikonzera machira emhando yepamusoro ane simba rakanaka uye akafanana. Mukudhaya machira, DMF inoshandiswa kuvandudza kunyungudika kwemachira, zvichiita kuti machira awedzere kushanda zvakanaka uye akaenzana.
Muindasitiri yemishonga, DMF ine basa rakakosha. Inowanzoshandiswa senzira yekunyungudutsa uye yekupindura mukugadzirwa kwemishonga yakasiyana-siyana uye mishonga yepakati. Kukwanisa kwayo kunyungudutsa mhando dzakasiyana dzemakemikari emuchadenga kunoita kuti ive sarudzo yakanaka yekubatsira kuita makemikari akaomarara, zvichibatsira kuvandudza goho uye kuchena kwezvigadzirwa zvekupedzisira. Makambani emishonga anovimba nemhando yepamusoro uye kugara kwenguva refu kweDMF yedu kuti ave nechokwadi chekuchengetedzwa uye kushanda zvakanaka kwemishonga yavo.
Indasitiri yemagetsi inobatsirwawo neDMF yedu. Inoshandiswa mukugadzira masemiconductors nezvikamu zvemagetsi. DMF inoshandiswa kuchenesa nekunyungudutsa zvinhu zvinodzivirira kupisa, zvichiita kuti patani yacho ive chaiyo uye mifananidzo ine resolution yepamusoro mukugadzira macircuit akabatanidzwa. Kusagadzikana kwayo kwakaderera uye simba rayo rakanaka rekugadzirisa kupisa zvinoita kuti ive solvent inokosha kuchengetedza mhando uye mashandiro emidziyo yemagetsi.
Pamusoro pezvo, DMF inoshandiswa muindasitiri yematehwe. Inoshandiswa mukugadzirisa dehwe kuti rive rakapfava uye rinochinjika. DMF inobatsira kunyungudutsa nekubvisa zvinhu zvisingadiwe kubva padehwe, ukuwo ichibatsirawo kupinda kwedhayi nezvinhu zvinopedzisa, zvichiita kuti zvigadzirwa zvedehwe zvive nerunako rwakawedzerwa uye chitarisiko chazvo.

Muchidimbu
DMF yedu yepasi rose - Premier yakaputirwa mumidziyo yemhando yepamusoro, isina mhepo yakawanda kudzivirira kusvibiswa uye kuona kuti yakachengeteka panguva yekuichengeta nekutakura. Batch yega yega inoongororwa zvakanyanya, kusanganisira kuongororwa kwekuchena kwayo, hunyoro, uye hunhu hwemakemikari. Ungave uri mugadziri wemachira muAsia, kambani yemishonga muEurope, kambani yemagetsi muNorth America, kana mugadziri weganda muAfrica, DMF yedu ndiyo solvent yakavimbika uye inoshanda yawanga uchitsvaga. Inopa mashandiro asina muganho uye kugadzikana, ichizadzisa zvinodiwa zvakasiyana-siyana zvemaindasitiri akasiyana uye ichikubatsira kuwana mhedzisiro yakanaka mumabasa ako ekugadzira.
