Abstract: De Application de domesticishydroxypropyl methylcelluloseInstead of importari unum ad productionem PVC cum princeps polymerization gradu introducta. Effectus duas species hydroxypropyl methylcellulose in proprietatibus PVC cum alta polymerization gradu investigari. Eventus ostendit quod factum est ut substituere domesticis hydroxypropyl methyl cellulosis enim importari unum.
High-gradu-of-polymerization PVC resins ad PVC resins cum mediocris gradu polymerization plus quam 1,700 vel cum paulo transire, coniunctum structuram inter moleculis, in quibus maxime commune sunt PVC in 2,500 [I]. Comparari cum Ordinarius PVC resinae, summus polymerization PVC resin habet altum mollitiam, parva compressionem set, bonum æstus resistentia, canus resistentia, lassitudine resistentia et gerunt resistentia. Est idealis Flexilis substitutum et potest esse in automobile sectore denudat, filis et funem, medicinae Catheters, etc [II].
Productio modum PVC cum princeps gradus polymerization est maxime suspensionis polymerization [3-4]. In productio ex suspensionis modum, quod est momenti auxiliorum agens, et eius genus et quantum voluntas recta afficit particula figura particula magnitudine distribution, et plasticizer absorbet de complevit PVC resinae. Communiter Systems Systems sunt polyvyl alcohol systems et hydroxypropyl Methylcellulose et polyvyl alcohol composita dispersionem systems, et domesticis artifices plerumque uti hoc [V].
I principalis rudis materiae et cubits
Pelagus rudis materiae et cubits usus est in test ostenduntur in Tabula I. Potest videri ex mensa I, quod domesticis hydroxypropyl Methylcellosus lectus in hoc charta est cum importari hydroxypropylt in hoc charta est cum importari hydroxypropyl, quod praebet in hoc quodammodo substitutionem test in hoc quod praebet in hac substituto charta.

II. II test methodo
In X l parvis test fabrica, uti importatur hydroxypropyl methyl cellulosis ad mores bencharmark probat determinare basic formula parva test; Usus domesticis hydroxypropyl methyl cellulosa reponere importari hydroxypropyl methyl cellulosis ad temptationem; PVC resinae products produci per diversas hydroxypropyl methyl cellulosis erant comparari ad studere replacement feasibilitatem de domesticis hydroxypropyl methyl Cellulose. Secundum eventus parva test, productio test peragitur.
II. III test gradus
Antequam reactionem mundare polymerization ollae claudere imo valvae, adde quodam moles desalinated aquam et addere dispersant; Claudere operculo in ollae vacuoize post transiens NITROGENIUM pressura test et deinde addere Vinyl chloride monomer; Post frigus turbantes, adde initiator; Uti aquam motu aquam ad temperatus in ollae ad reactionem temperatus, et adde Ammonium bicarbonate solutio in opportune modo in hoc process ad adjust phale de reactionem ratio Cum reactionem pressura guttae ad pressura certa in formula, addere terminandi agente et defoaming agente, et missionem et complevit productum de PVC resinae est adeptus a centrifugaci et siccatio, et sampled in analysis.
II. IV Analysis modi
According to relevant test methods in enterprise standard Q31/0116000823C002-2018, the viscosity number, apparent density, volatile matter (including water) and plasticizer absorption of 100 g PVC resin of finished PVC resin were tested and analyzed; Mediocris particula magnitudinem PVC resinae temptavit; In Morphologia PVC resin particulas observata usura a scanning microscopium.

Potest videri a mensa III quod usus est domesticis hydroxypropyl methylcellose paulatim aucta ad omnes batches de domesticis hydroxypropyl Methylcellosus repositum importari hydroxypropyl methylcellosa. Pelagus Indicatores ut plasticizer effusio et apparent densitas non fluctuare significantly, indicando quod domesticis hydroxypropyl methylcellosus lectus in hoc paper potest reponere in productio hydroxypropyl
IV conclusioni
In test de domesticishydroxypropyl methyl CelluloseDe X l parvis test fabrica ostendit quod habet in feasibility reponere importari hydroxypropyl methyl Cellulose; Productio substitution test eventus ostendere quod domesticis hydroxypropyl methyl Cellulose adhibetur pro PVC resinae productio, pelagus species Indicatores de perfecta PVC resinae et importari hydroxypropyl In praesenti, pretium domesticis Cellulose in foro est inferior, quam ut de importari Cellulose. Ideo, si domesticis Cellulose adhibetur in productione, sumptus productio AIDS potest significantly reducitur.
